In another life, I manage five Win98 workstations. Three are at home and for the most part give me no trouble. Two are in my wife's lab, and recently one of them began giving her [and, naturally, me] trouble.
It seems that it didn't automatically adjust for Daylight Savings Time. So I manually adjusted it, but noticed that instead of Eastern Time, it was set to Pacific Time. So I adjusted that as well. [Specifically, I double clicked on the digital clock display in the right side of the taskbar, and then adjusted
both the timezone and the DST checkbox appropriately]. This was mid-
aftrnoon on Sunday, 2 April, 2000.
Every morning it's back to Pacific time. No explanation. Nothing in the
startup group to trigger something like an NTP client to resync, besides the
fact that if I'd ever installed such a client there (I DO have Dimension4 installed on some of those other Win98 boxes noted), I'd have pointed it to the same clock server that I have my Novell, VMS, Unix and NT servers all
beholden to [and those Dimension4 Win98 workstations I admitted to],
and all of them have the correct time.
Machine is Win98 second edition with (as of yesterday) ALL Microsoft Critical Updates applied.
