Apex clock problem

[C4DC]

My Apex has been having difficulty keeping time. I had it running manually without hitch up until a couple days ago when it left the lights on all night. I couldn't even manually turn them on or off from the controller or access the unit via computer. Through rebooting the system to get it online via the ethernet/computer, I was able to reset and everything seemed fine.
Come home for lunch today and the lights were off-Clock was back in 2007, and since then I've tried every combination of auto set, manual set etc without avail. With auto set I'm -5 (and it picks up the date/time correctly), but when I cut the power to the system and re-plug and reset, it insists on -9. With manual set, a reboot gets reset for several years ago at a totally different time.
Sucks beacuse were supposed to leave for the weekend, but can't until I get this figured out or whip out the timers.
What do you guys think is up with the clock?

I don't think it's your clock. More likely, it's the internal battery that keeps time during a reboot or power failure. Unfortunately if that's the case, it's not user replaceable and requires a trip out to California.
