I've been having weird problems with my motherboard. Occasionally the motherboard's time sets itself a few hours forward on while turning on, but not every time. The actual date and all of my motherboard settings are being retained, but not the time. Anyone know why this is happening?

Try changing the bios battery if that doesnot help update the bios.
You may need to fix your time-zone on your computer. Assuming you're running Windows 7:
Click the clock on the task bar -> Select "Change date and time settings" -> Change Time Zone
