Try this one on for size,
I was not able to run the patch on my system so I gave it up for lost, then came the message(just after the original DST date) that my clock had been reset.
I was very surprised to find out that it was 9:02 am Feb. 4, 1980

(oh man I have to go back to the 7th grade, that sucks (lol)).
Needless to say I downloaded the atomic clock and now my date and time stay right here in the future where they belong.
