random clock restart on restart on early 2009 MBP

[Hipnomac]

I restarted my computer, and when it booted back up the clock was reset to Dec 31 2000. I did not change the clock, and my control settings are password locked.

Should I be concerned about this, and has this happened to anybody else?

Thanks.

Happened to me a few days ago - restarted and all was back as normal.

I assumed I dreamt it cos Macs "just work".

Yep. Reboot while holding down Command, Option, P, and R. You'll hear a second startup chime after a few seconds. Keep holding them down until you've heard three or four, then release them to boot normally.
