I'm not rebooting the system when this happens, and I don't believe that the cmos battery is dead, because just the date changes and not the time. This happened yesterday 9/15/02 at about 1PM. I have atomic clock installed on the system, but from time to time it can't reach the time server. The strange thing is that the date changed on September, 17, 2002 also, and it is just the date and not the time. I have check the time zone settings and they are correct. Thanks for the help in advance.
