The system clock (in the lower right corner of my screen) just started jumping backwards 26 minutes. It's always 26 minutes late. When I change it to the correct time, it changes back immediately. When I play with the time zones, it doesn't fix it. When I sync to a time server, it just jumps back to 26 minutes late again. I am not connected to any type of DHCP server. This is my home/business PC. It is a new computer (less than a month old) so I doubt the internal battery is going bad. What else could be causing this?
