The only battery I know of in a desktop system is the battery that keeps your bios settings when you turn the CP off. Until you replace that one everytime you start the PC it will use the default settings in you bios and ignore any changes you have made.
System date and time are one of those settings.
Unlike a battery operated clock, a low battery will not cause the PC clock to run slow. Some systems, and I have one, do not keep accurate time for one reason or another. This is especially true of Win95, Win98 and Win ME systems. XP has a built in routine that automatically syncronizes the clock as necessary every time you go online.
You can also download a time server program that will keep your PC clock accurate. One such program is Atomic Clock Sync, available at worldtimeserver.com
Hope this helps.
