The Mars Explorer Rover team will be sending a wake-up call to the Spirit rover between 2:30 and 3 PM this afternoon. I just found a nifty Martian time calculator over at the Goddard NASA pages. You can use it to display the time and a very cool sunclock that will show you (if you look at it now) the sunrise at Gusev crater where Spirit is awaiting its wake-up call.
Commentary/coverage of the wake-up call is underway on NASA TV.
