Clock goes back in time

zwatch

The clock is always slow. When I change the date and time it shows the correct time while the computer is on. The problem may be when it's turned off because the next day it's always many hours slow and usually a day behind.

Hardware issue. Weak CMOS battery on the motherboard is the usual cause.
