Do you play music Dave, or is listening your primary enjoyment?

I was a musician - played guitar and sang with others. Taught myself keyboard, played recorder as a kid, fiddled with a mouth organ and accordion.
All good fun!


Thanks for the gettimestamp update...

I used to sing a lot with various choral groups, the most satisfying being the Baltimore Choral Arts Society, and the Baltimore Symphony Chorus. But I've pretty much given up singing for the moment.

For the past 6 years I have been playing Native American flutes, mostly at open mics. It's all improvisation. I especially like to jam with one or more additional musicians. A slow week I may play only once. But recently I've been active as much as 5 nights in one week.

I have a bunch of music posted to the internet:
The host of my favorite open mic has posted a handful of my performances within his "Favorite Open Mic moments" playlist
I've got 40+ videos I've posted myself on my YouTube channel
And I have over 3+ hours of music posted on my SoundCloud page at http://soundcloud.com/dave-benham
There are additional videos others have posted of me out there somewhere.

My oldest son is on year 8 singing with the Green Bay Boy Choir and my youngest joined this year as well. They went to sing in Austria and the Czech Republic last year.

I love the gentle sound of the flute Dave. You and your companions make lovely music.

That can only be a great experience for them Squashman. Making music is a highlight in my life, and I'm sure they will treasure it into the future too.

Foxidrive,
Thanks for the link. I'm sure someone could probably use that script to code part of what I'm trying to accomplish but for me it is beyond my current experience level to understand it and then write the additional code required to use it in the way I need in any kind of timely manner.

I'm really looking for something a bit more "turn key" that I can just copy and plug-in to my batch file. If you have any additional examples that are a little closer to my requirements or can put together something that specifically targets what I need then that would be fantastic.

Mike

It doesn't get much more turnkey than getTimestamp.bat.

You need to know the date and time format used by your locale. For me I need mm-dd-yyyy and hh:mm:ss.ff, where hh is in 24 hour format, and .ff is optional fractional seconds. Also, you must be running as administrator if you want to modify your computer's system date/time.

Code: Select all

for /f "tokens=1,2" %%A in (
  'gettimestamp /oh -3 /f "{mm}-{dd}-{yyyy} {hh}:{nn}:{ss}"'
) do date %%A & time %%B

Dave, I have a task to add these times one-by-one and get a cumulative result from each step, but also adding the day in a 2 digit zero padded figure.

Can you give me a clue please?

Couldn't you just convert the entire timestamp to seconds and do math that way?

That's the hard bit for me. I have panic attacks when I have to add 3 cents and 4 cents at the supermarket.

It would need to be done in milliseconds and I don't understand all the complexity in gettimestamp.bat
Maybe jeval.bat would be better but my brain is still not up to the task.

This post is for releasing getTimestamp version 2.5

I discovered a significant bug with version 2.4 when doing date/time offset computations where the local timezone of the original value is different than the local timezone of the result due to daylight savings issues.

Here is a simple loop that demonstrates the 2.4 bug

Code: Select all

C:\test>for /l %M in (0 1 12) do @getTimestamp -d "'1/1/2016 UTC'" -od %M*30 -u
2016-01-01T00:00:00.000+00:00
2016-01-31T00:00:00.000+00:00
2016-03-01T00:00:00.000+00:00
2016-03-30T23:00:00.000+00:00
2016-04-29T23:00:00.000+00:00
2016-05-29T23:00:00.000+00:00
2016-06-28T23:00:00.000+00:00
2016-07-28T23:00:00.000+00:00
2016-08-27T23:00:00.000+00:00
2016-09-26T23:00:00.000+00:00
2016-10-26T23:00:00.000+00:00
2016-11-26T00:00:00.000+00:00
2016-12-26T00:00:00.000+00:00
My base timestamp is midnight, Jan 1, 2016 UTC, and I add multiples of 30 days. My local time zone is the U.S. Eastern Time, which follows daylight savings. The time should remain midnight throughout. But notice how the daylight savings months are off by an hour :!: :(

The fix was quite simple. I just had to make sure I always use the UTC functions whenever I perform date computations

So here is the correct result using version 2.5:

Code: Select all

C:\test>for /l %M in (0 1 12) do @getTimestamp -d "'1/1/2016 UTC'" -od %M*30 -u
2016-01-01T00:00:00.000+00:00
2016-01-31T00:00:00.000+00:00
2016-03-01T00:00:00.000+00:00
2016-03-31T00:00:00.000+00:00
2016-04-30T00:00:00.000+00:00
2016-05-30T00:00:00.000+00:00
2016-06-29T00:00:00.000+00:00
2016-07-29T00:00:00.000+00:00
2016-08-28T00:00:00.000+00:00
2016-09-27T00:00:00.000+00:00
2016-10-27T00:00:00.000+00:00
2016-11-26T00:00:00.000+00:00
2016-12-26T00:00:00.000+00:00


And here is getTimestamp version 2.5

:::getTimestamp  [-option [value]]...
:::
:::  Displays a formatted timestamp. Defaults to the current local date
:::  and time using an ISO 8601 format with milliseconds, time zone
:::  and punctuation, using period as a decimal mark.
:::
:::  Returned ERRORLEVEL is 0 upon success, 1 if failure.
:::
:::  Options may be prefaced with - or /
:::
:::  All options have default values. The default value can be overridden by
:::  defining an evironment variable of the form "GetTimestamp-OPTION=VALUE".
:::  For example, upper case English weekday abbreviations can be specified as
:::  the default by defining "GetTimestamp-WKD=SUN MON TUE WED THU FRI SAT".
:::
:::  Command line option values take precedence, followed by environment variable
:::  defaults, followed by built in defaults.
:::
:::  The following options are all case insensitive:
:::
:::    -?  : Prints this documentation for getTimestamp
:::
:::    -?? : Prints this documentation with pagination via MORE
:::
:::    -V  : Prints the version of getTimeStamp
:::
:::    -D DateSpec
:::
:::       Specify the base date and time.
:::       Default value is current local date and time.
:::       The DateSpec supports many formats:
:::
:::         ""    (no value)
:::
:::           Current date and time - the default
:::
:::         milliseconds
:::
:::           A JScript numeric expression that represents the number of
:::           milliseconds since 1970-01-01 00:00:00 UTC.
:::           Decimal values are truncated.
:::           Negative values represent dates prior to 1970-01-01.
:::
:::         "'Date [Time] [TimeZone]'"
:::
:::           A string representation of the date and time. The date information
:::           is required, the time and time zone are optional. Missing time info
:::           is assumed to be 0 (midnight). Missing time zone info is assumed to
:::           be local time zone.
:::
:::           The Date, Time, and TimeZone information can be represented as any
:::           string that is accepted by the JScript Date.Parse() method.
:::           There are many formatting options. Documentation is available at:
:::           http://msdn.microsoft.com/en-us/library/k4w173wk(v=vs.84).aspx
:::
:::           Examples of equivalent representations of Midnight on January 4,
:::           2013 assuming local time zone is U.S Eastern Standard Time (EST):
:::
:::             '1-4-2013'                    Defaults to local time zone
:::             "'January 4, 2013 EST'"       Explicit Eastern Std Time (US)
:::             "'2013/1/4 -05'"              Explicit Eastern Std Time (US)
:::             "'Jan 3 2013 23: CST'"        Central Standard Time (US)
:::             "'2013 3 Jan 9:00 pm -0800'"  Pacific Standard Time (US)
:::             "'01/04/2013 05:00:00 UTC'"   Universal Coordinated Time
:::             "'1/4/2013 05:30 +0530'"      India Standard Time
:::
:::         "year, month[, day[, hour[, minute[, second[, millisecond]]]]]"
:::
:::           A comma delimited list of numeric JScript expressions representing
:::           various components of date and time. Year and month are required,
:::           the rest are optional. Missing values are treated as 0.
:::           Decimal values are truncated. A 0 month represents January.
:::           A 1 day represents the first day of the month. A 0 day represents
:::           the last day of the prior month. The date/time value is always
:::           in local time. There is no mechanism to specify a time zone.
:::
:::           Examples: (all in local time)
:::             "2012,0,1,12,45,3,121"  12:45:03.121 on Jan 1, 2012
:::             "2012,0,1,12"           Noon on Jan 1, 2012
:::             "2012,1,1"              Midnight on Feb 1, 2012
:::             "2012,2,0"              Midnight on Feb 29, 2012 (last day of Feb)
:::             "2012,2"                Midnight on Feb 29, 2012 (last day of Feb)
:::
:::           The ability to use JScript expressions makes it convenient to do
:::           date and time offset computations in a very compact form.
:::
:::           For example, starting with:
:::             "2015,8,7,14,5"        Sep 7, 2015 at 14:05:00
:::
:::           It is simple to subtract 30 days and 30 minutes from the above:
:::             "2015,8,7-30,14,5-30"  Aug 8, 2015 at 13:35:00
:::
:::    -U  : Returns a UTC timestamp instead of local timestamp.
:::          Default is a local timestamp.
:::
:::    -Z TimeZoneMinuteOffset
:::
:::       Returns the timestamp using the specified time zone offset.
:::       TimeZoneMinuteOffset is a JScript numeric expression that
:::       represents the number of minutes offset from UTC.
:::       Decimal values are truncated.
:::       Default is empty, meaning local timezone.
:::
:::    -OY YearOffset

It is fairly straight forward (once you have my v2.5 release that fixes a bug with offset computations).

You need to do the computations as miliseconds past midnight 1/1/1970 UTC.

The standard string date parser recognizes dates like 'mm/dd/yyyy HH:MM:SS UTC', but unfortunately it does not recognize fractional seconds. So you need to add the fractional seconds using the -OF option. You also keep a running tally of the total milliseconds, which needs to be added to each value as well. I initialize my total to 0 at the start.

So I use a simple FOR loop to iterate the raw strings, and a FOR /F to separate the fractional seconds from the rest of the time.

Note that JScript treats 0 prefixed numbers as octal (unless it sees an 8 or 9 digit, in which case it switches to decimal - very screwy). So I use the standard trick of prefixing the string with 1 and then subtracting 1000.

So the first JREPL treats the time interval as the number of milliseconds past midnight 1/1/1970 UTC, and also adds the previous total value, and stores the result as the new total.

The 2nd JREPL simply formats the time value appropriately. I don't have a built in way to specify the number of digits to display for the {UD} value, so I use the standard trick of prefixing the value with leading zeros, and then use a variable substring op to get the correct value.

The technique can easily be extended to support day values in your input. I add the days into the computation using the -OD option. Obviously I had to modify my loop parsing a bit. I opted to set my day width to 3 characters, with leading spaces instead of zeros.

Re: getTimestamp.bat for time and date processing

#42 Post by dbenham » 10 Jul 2016 12:33

My last version fixed a problem with the date/time offset options, but it also lost the ability to add days or months without changing the local time. Adding days and months results in a change that is an exact multiple of 24 hours, so the local hour may change if the daylight savings conditions changes.

For example, if the timestamp were 1AM on 1/10/2016 on the U.S. coast where I live (6:00 UTC), then use of -OM 6 (add 6 months) would result in a local time of 2AM instead of 1AM because of the switch-over from standard time to daylight savings. Note that UTC time would be perfectly fine, since it does not observe daylight savings - the UTC time would remain at 6:00.

I've added the -OLM and -OLD options to allow addition of local months and days in a way that preserves the local hour. Thus the change may not be an even multiple of 24 hours. So going back to my example of 1/10/2016 1:00 AM EST, adding -OLM 6 would preserve the local time of 1:00 (but the UTC time will have gone from 6:00 to 5:00).

::getTimestamp.bat version 2.6 by Dave Benham
::
::  Release History:
::    2.6 2016-07-10 - Added -OLM and -OLD to allow addition of months/years
::                     without changing the local hour. In other words, the
::                     computation compensates for changes in dayling savings
::                     conditions.
::    2.5 2016-07-09 - Fixed bug with offset computations when the before and
::                     after have different time zones due to daylight savings.
::    2.4 2015-11-27 - Added formats to support comma as decimal mark in
::                     ISO 8601 time and timestamp formats.
::                     Added formats to support ISO 8601 week dates
::                     and ordinal dates.
::                     Rearranged documentation, and added examples for
::                     base date specified as a list of numeric values.
::    2.3 2015-07-11 - Added {ISO-xx}, {ISOxx}, {DY} and {DDY} formats
::                     Added -?? (paged help) option
::                     Allow user defined default option values by defining
::                     variables of the form "GetTimestamp-OPTION=VALUE"
::    2.2 2014-12-03 - Doc fix: -R ReturnVariable is unchanged if err occurs
::    2.1 2014-12-03 - Added GOTO at top to increase performance (32% faster)
::    2.0 2014-12-02 - Major rewrite: most code now in JScript (25% faster)
::                     Better error handling
::                     May now use /Option or -Option

::============ Documentation ===========
:::
:::getTimestamp  [-option [value]]...
:::
:::  Displays a formatted timestamp. Defaults to the current local date
:::  and time using an ISO 8601 format with milliseconds, time zone
:::  and punctuation, using period as a decimal mark.
:::
:::  Returned ERRORLEVEL is 0 upon success, 1 if failure.
:::
:::  Options may be prefaced with - or /
:::
:::  All options have default values. The default value can be overridden by
:::  defining an evironment variable of the form "GetTimestamp-OPTION=VALUE".
:::  For example, upper case English weekday abbreviations can be specified as
:::  the default by defining "GetTimestamp-WKD=SUN MON TUE WED THU FRI SAT".
:::
:::  Command line option values take precedence, followed by environment variable
:::  defaults, followed by built in defaults.
:::
:::  The following options are all case insensitive:
:::
:::    -?  : Prints this documentation for getTimestamp
:::
:::    -?? : Prints this documentation with pagination via MORE
:::
:::    -V  : Prints the version of getTimeStamp
:::
:::    -D DateSpec
:::
:::       Specify the base date and time.
:::       Default value is current local date and time.
:::       The DateSpec supports many formats:
:::
:::         ""    (no value)
:::
:::           Current date and time - the default
:::
:::         milliseconds
:::
:::           A JScript numeric expression that represents the number of
:::           milliseconds since 1970-01-01 00:00:00 UTC.
:::           Decimal values are truncated.
:::           Negative values represent dates prior to 1970-01-01.
:::
:::         "'Date [Time] [TimeZone]'"
:::
:::           A string representation of the date and time. The date information
:::           is required, the time and time zone are optional. Missing time info
:::           is assumed to be 0 (midnight). Missing time zone info is assumed to
:::           be local time zone.
:::
:::           The Date, Time, and TimeZone information can be represented as any
:::           string that is accepted by the JScript Date.Parse() method.
:::           There are many formatting options. Documentation is available at:
:::           http://msdn.microsoft.com/en-us/library/k4w173wk(v=vs.84).aspx
:::
:::           Examples of equivalent representations of Midnight on January 4,
:::           2013 assuming local time zone is U.S Eastern Standard Time (EST):
:::
:::             '1-4-2013'                    Defaults to local time zone
:::             "'January 4, 2013 EST'"       Explicit Eastern Std Time (US)
:::             "'2013/1/4 -05'"              Explicit Eastern Std Time (US)
:::             "'Jan 3 2013 23: CST'"        Central Standard Time (US)
:::             "'2013 3 Jan 9:00 pm -0800'"  Pacific Standard Time (US)
:::             "'01/04/2013 05:00:00 UTC'"   Universal Coordinated Time

:::
:::         "year, month[, day[, hour[, minute[, second[, millisecond]]]]]"
:::
:::           A comma delimited list of numeric JScript expressions representing
:::           various components of date and time. Year and month are required,
:::           the rest are optional. Missing values are treated as 0.
:::           Decimal values are truncated. A 0 month represents January.
:::           A 1 day represents the first day of the month. A 0 day represents
:::           the last day of the prior month. The date/time value is always
:::           in local time. There is no mechanism to specify a time zone.
:::
:::           Examples: (all in local time)
:::             "2012,0,1,12,45,3,121"  12:45:03.121 on Jan 1, 2012

:::             "2012,2"                Midnight on Feb 29, 2012 (last day of Feb)
:::
:::           The ability to use JScript expressions makes it convenient to do
:::           date and time offset computations in a very compact form.
:::
:::           For example, starting with:
:::             "2015,8,7,14,5"        Sep 7, 2015 at 14:05:00
:::
:::           It is simple to subtract 30 days and 30 minutes from the above:

Re: getTimestamp.bat for time and date processing

#43 Post by foxidrive » 06 Aug 2016 07:43

Dave, can I ask you to run your eyes over this please? I think 2 litres of Glenfiddich has detuned my brain. ;)

I found out that Matroska chapters in MKV files don't support day figures, and instead increment the hour figure when the total is over a day: so 25 hours is one day and one hour.

That's what my aim is: to accumulate the hour range instead of what you see here where the hours accumulate to one day and then begin at 01 again.


Do you have some wizardry up your sleeve to handle this?


I noted a strange effect in a few spots where the total is only few minutes different for a 45 odd minute chapter. Or is that my error?

If you read the documentation, you will see that the /Z option should not be used with any of {UMS}, {US}, {USD}, etc. I believe it actually works if the /Z (timezone offset in minutes) is 0, but a better alternative is to use the /U option.

All you need is {UH} to get the number of whole hours (no rollover at 24). Note that it does not pad to a specific width because there is no limit to how many digits might be required.

Code: Select all

call getTimestamp /d "'1/1/1970 01:32:21 UTC'" /of 101140212 /u /f "{ums} {uh}:{nn}:{ss}.{fff}"


I'm not sure what strange effect you are referring to. You will have to give me a specific example, describing what you expect vs. what you see.

Thanks Dave, that's spot on and I'm able to remove all the kludgey code I was trying to make work.


I'm finding sustained concentration a bit challenging at the moment due to illness.

The odd lines are shown below with the code from my question - they disappeared with your fix.
