I just re-read the pertinent paragraph:
The FAT file system records times on disk in local time. GetFileTime
retrieves cached UTC times from the FAT file system. When it becomes
daylight saving time, the time retrieved by GetFileTime is off an hour,
because the cache is not updated. When you restart the computer, the
cached time that GetFileTime retrieves is correct. FindFirstFile
retrieves the local time from the FAT file system and converts it to UTC
by using the current settings for the time zone and daylight saving
time. Therefore, if it is daylight saving time, FindFirstFile takes
daylight saving time into account, even if the file time you are
converting is in standard time.
Sounds like a restart is needed to ensure that the APIs the engine has
to use are correct...
