My system clock stopped working, so I obvious take out the battery and off to Radioshack and bought a new one, of the same type. I put it in fine, and its back up and running. The problem is say 4 times in the last month(seems to be random at the moment), I decide to look down at my clock only to notice, its exactly 3 hours slow. Does anyone have any thought as to why it might be reacting this way? I still have yet to determine if I'm doing something specific to set it off, and before on my old battery, i had no issue. I'm clearly writing about it now, because i just realized it happened again. Thanks for any input.
