Time Keeping

[Andypc]

Minor question, I set the time and date on several of my Bally / Williams games, over a few weeks some of them are losing time. They all had new batteries in. Just wondered if this is normal?

Losing time as in being completely off, or losing a minute here or there?

Losing an hour or more over a few weeks

I think it is normal, and may be due to the u.k. having a different mains frequency from the usa. I used to set games not to display their idea of the time in attract mode due to inaccuracy

I lose the odd minute here and there on TZ over several weeks, but not hours.

Have you tried replacing the batteries? Are you using a Rottendog CPU board?
