Time differences of 1 hour

[fixmypcmike]

Different decompression utilities for .zip files sometimes result in files with time differences of 1 hour, presumably depending on daylight savings time settings of the computer on which the zip was created and/or the computer on which the files are extracted. Is there any option in Winmerge to ignore differences of 1 hour when comparing folders by Modified Date and Size?

Unfortunately, WinMerge does not have an option to ignore timestamp differences caused by Daylight Saving Time.

The 1-hr time difference between NTFS/FAT DST and STD time has been the biggest announce with WinMerge. I like WinMerge a lot but you need to include this feature.
The date, minutes and seconds are the same but the hour is different. If you could have an option where you ignore the hour for date-time compare. that would cover 99% of all files, except for ones modified around midnight.

The hour should not be completely ignored, only if the difference is exactly one (1) hour should the files be considered identical.
And it should be configurable to the user if he wants the 1-hr time difference being ignored or not.

@fixmypcmike: it does not only affect zip files, but also e.g. jpg- and mp4-files.

Boar24, Agreed, that this feature (ignore time difference of one hour) should be an option, just like "check only on size". Case in point, we had a time change couple weeks back and my 14GB of backup on a Flash drive had to be unnecessarily re-written because of the time change. Mike L.
