date time subtraction

#1 Post by perinho » 17 May 2018 05:43

I want to create a batch file that will read a string of numbers (e.g. 20180517120101) from inside a text file (e.g. C:\Users\Public\Documents\Admin\exetime.txt) and recognize these as date and time (yyyyMMddHHmmss)
the batch file will then subtract the current time from this, and write the answer into another text file (e.g. C:\Users\Public\Documents\Admin\elapsed.txt)
The answer would preferably be in days (e.g. 0.2 or 64)

I have a low level knowledge of coding and wondering is this even possible?
If this is possible, a solution would be fantastic.

Many thanks.

I would use Dave's JTimeStamp script to calculate the date and time offset.
