I get this too, I think because I am in Britain where we switch between GMT and BST time (1 hour difference) depending on the time of year, when this happens to me it tends to relate to, I think, Windows and Linux trying to handle the timezone in a different way to compensate for this.
I also had a really weird event once where after having been using a live USB I booted windows on the hard-drive and found the dates to be showing as the year 11000 or so. It was quite amusing to see how everything was going really slow, I guess because Windows was having to do a lot more work on many more digits every time a time or date calculation was done, but it was all fixed after resetting the clock to the true date and restarting windows a few times. Unfortunately I never had the presence of mind to try opening some software on windows while the future date was set to several millenia away, would have been interesting to see which things would have been able to survive the 2038 problem or year 10000 problem.
