Not originally, and not intentionally, as I am always careful about 
this on installation. It is not inconceivable, though, that 
something was changed during an upgrade.

Yes, I am dual-booting, and no doubt this is probably the thing I 
should check into. I *have* been dual-booting for almost ten years 
though, and have never had these problems before, which is why I am 
befuddled by the sudden appearance of this problem. However, when I 
go to my office next time, I'm going to carefully check the time 
setting on both Debian and XP.

This most recent event seems to indicate that.

When I first began using Linux, there was little, if any NTFS 
support, so I kept running my Windows systems on FAT for a long 
time. For the machines that I've bought most recently, I'm leaving 
them as NTFS. No problems.

Thanks,
