My 2011 Macbook Pro's battery died. I plugged it in, and it turned back on. After starting up, I got a message saying:

Your computer's clock is set to a date before January 1, 2008. This may cause some applications to behave erratically.

And my clock & date was, in fact, set to an incorrect time and some date in 2000. I just corrected the date and it was fine.

Any idea why this happened/if it's a sign of a problem?
