Bad Clock Detector for Mac

From bbum:

It annoyed me that everytime I lost power to my TiBook, the clock would reset to 1970, I would forget to reset it and a bunch of people would make fun of me for sending email from the distant past. Worse, some people sort their email by date and, as such, never noticed that I sent them email that their mail client thinks is from Jan 1, 1970.
This silly little bit of AppleScript can be installed as a login item under OS X and will automatically launch System Preferences and select the Date & Time preferences pane if the year of your system's clock is preposterous (as in, prior to 2002).
