Clock's gone cuckoo?

[Pursuit]

After working on the car a bit (including disconnecting battery and pulling ECU), my clock won't keep the time. All the OBC functions work, and it lights and sets normally but then when the car is turned off it loses the time and goes to an apparently random time.

Anyone had a similar problem and figure it out?

EDIT: I kept neglecting to push the S/R button after setting the time, to start the clock running... :redface:
