Hey again,
I wanted to give you all an update: The machine was sent off to apple (by the reseller I got it from) where they supposedly replaced the power supply and logic board.
The question is, +did they replace the clock battery?+

Two weeks went by with no problems, then when switching to the high performance gfx card last night, I logged back in to be greeted with the same problem!
Seems the clock only resets on boot, then.

New information- I had reset the clock to do a time machine backup before taking it in. Once at the store- the problem couldn't be repeated - until I clicked "automatically set date and time", then viola, all the errors returned.
Hmm. When
I clicked “automatically set date and time” and logged out, then logged back in, all of the errors were solved.

I'm going to try my best to get an exchange, assuming it is in fact hardware. Good luck.
My guess is that the battery that keeps the internal clock running is failing. When the computer is on, the clock runs from the normal battery, right? Then on shutdown, it switches to its own battery, right? That would make sense: if the clock battery is failing, the time would be okay while the computer is on because it'd be relying on the normal battery, which seems to be fine in all of our cases. When the computer shuts down|reboots, the clock would switch to its own battery, which would not supply it power, having failed. The clock would then do its version of blinking 0000; resetting to before 2008. That would cause the symptoms outlined earlier in this thread.
