It's Working!
Come October, for the first time in 6 years, it will make the
transition without trouble.

Thank you for the pushes in the right directions.

const DWORDLONG DayLightAdjust = 0x000000861c46800;
BOOL DayLight = (TIME_ZONE_ID_DAYLIGHT==GetTimeZoneInformation(&tzi));
	GetVolumeInformation(.....)
BOOL FAT = (0==memcmp("FAT",FileSystemName,3));

	if( DayLight && FAT )
/*doesn't compile, but you get the idea */
		fcb.ftCreationTime += DayLightAdjust;

No, XP returns different times depending on if the 98 host is in DST
or not. So, above code will still work.
