Why doesn't my computer stay in the same time zone?

Episode 1366 (1:05:57)

Bret from Woodbridge, NJ
Motherboard battery

Bret has to constantly change the time on his computer because it keeps going back to another time zone. Leo says that he'll need to go into the settings and look for the time zone for his area. For New Jersey, it would be UTC-5. If the problem still perstists, then it could be a dying battery of the motherboard. That battery looks like a coin.
