The obvious conclusion is that your hardware clock stopped when you
powered the machine down! The clock, and the battery that powers it
when AC power is off, are encapsulated in the NVRAM chip on most Sun
hardware. If the hardware is old enough and has been powered off for
extended periods, the battery could be failing.
Try shutting down and entering "watch clock" at the OBP prompt. That
should show if the clock is still ticking and at what rate. If it's not
running or not ticking at approximately one second per second, have Sun
fix it!
The other possibility is that it was two hours off when you shut it
down! There is nothing at all to act as a check on the local clock!!!!!
