    After change to winter time every file is discovered as changed

    An old windows devil seems to be Back:
    After change to winter time every file is discovered as changed...
    (so LMS just tries to update 1.100 k entries in my DB...)

    Music stored on a FAT file system ?

    If so, file time stamps are by definition/convention interpreted as local time. So UTC value of time stamp changes when winter/summer time changes.

    On a Linux system, one can mount a FAT volume and specify that file time stamps always be interpreted as UTC. But of no help on a Windows system.

    No, on NTFS

    Yes, I know all of this. It happened constantly (every summer / winter time change) until maybe 5 or 6 years ago. Then Michael added a line that fixed it! I guess, this line became "cancelled" for some reason in between the last 6 months (for in march 2022 i guess it worked fine). I hope he remembers this "line" so it could be a quick fix... ;-)

    Should be this one:

    As You say, this is not a solution for windows systems

    Is this _all_ your library? When did the scan kick in? Could it be the
    time changed during the scan? What Windows version are you running?

    No, the time change was at 3:00AM in the night, at this time my pc was off and Out.
    I started the PC around 10:00AM and the scan (I always do it manually) about 7:00 PM I guess so there should be no connection.
    I'm running Windows 11 latest official build (22H2).
    Thanks for caring

    Work around (tested):
    - Stop LMS while scanning (by task manager)
    - Restart LMS
    ... I don't know why, but it works - may it be there has to be more than 12 hours or so after the "time change"?

    Rem.: Between stop and restart I installed today's nightly - but I don't guess there is already any fix for this in it...
