I use WinMerge for sync'ing my music and photo collections with their respective back-up stores.

This works fine, except twice a year all items are reported as "different".

This is due to the fact that one of the disks is a USB/FAT32 disk and the other is a NAS. The FAT32 disk uses "local time" stamping, and the NAS stamps files based on UTC, presenting local time.

The workaround is to accept making a complete copy twice a year, but this takes a long long time.

My request is to add a feature that allows a fixed time offset between source and destination.

Alternatively, you could extend the existing feature that allows a time difference of up to 3 seconds.
But I think this would be dangerous, as some differences would be ignored unintentionally.
So it would be better to have an exact time difference.
It could be offered as a drop down list of say, 30 minutes, 60 minutes, 90 minutes, 120 minutes.
Or it could be a freely editable offset if you want that flexibility. I'd say keep it simple ...

    Hello!
    I was about to suggest the same improvement when I found this ticket.
    I have the exact same problem and I like the suggested solution.
    I hope this will be implemented.
    Best,
    Luca

    This is something I could really use as well. Same kind of issue, I'm using a FreeBSD server running Samba & need to diff files & dirs between it and Windows boxes. The "off by exactly 1 hour" issue gets me all the time, if I have to do restores from tape.

    Ok, this is clearly something we must handle. I try to find some time for this.

    I need this feature too!! Urgent!
    timestamps with 1 hour +-3 seconds differencies should be recognizable and filterable

    thanks

    Another time change (winter)... another headache... :s
    A checkbox with "ignore DST difference" would be just great...
