The clock in our 2003 Corolla started shutting down intermittently and eventually gave up the ghost for good.
After looking around here and other forums and finding that they wanted hundreds (2-4?) for a new one at the dealer and even a fair chunk at the wreckers (if you can find it), I ended up finding this guy: http://www.subaru-clock.com/
$29.50 + initial shipping, he fixed it up, sent it back and good as new.
To get the clock out, pull the fan speed dial straight out and remove the phillips head screw. There are two screws at the bottom of the console you can remove if you want, but you can squeeze the clock out without it if you're careful.
Pull outwards on the console, unplug the clock, unsnap it from the face and you're good to go.
