Are you running this in a virtual machine? Do you have a setting in the virtual machine for keeping the clock synchronized with the host, and at the same time using NTP (Network Time Protocol) to keep your computer time up to date with the Internet?

You don't have two different NTP services running do you, conflicting with each other? You could have a system service and also be doing clock sync through the desktop (if your desktop environment supports it).

The clock works smoothly at other times? The time remains correct if the computer is turned off (the clock keeps running if you're plugged in or if your computer has a bios battery with power in it). Does it do this if you boot into an alternative operating system?
