George,
We had to run a special utility from Windows on all our Win2k clients and servers to reset the time zone. The file is called TZEDIT.exe date 12/2/1999 and I think our network admin downloaded it from Microsoft. It lets you reset the dates that the DST takes place.
I will email instructions our admin put together in a separate email to you so the file doesn't go to the list.
I saw what happened on my machine if this utility wasn't used. I could set my clock to the correct time but any files I used on another server showed the time as being a hour off, even though the problem was on my computer. When mine was correct the time showing from other servers was correct.
