Thanks, Phred! I always miss one or two, although I was pleasantly surprised to find my new DVD/VCR changed the time itself.

And as for smoke alarms, I always tell myself I'm going to do it, but seem to forget. This time they reminded me by going off - they beep when the batteries get low. So all clocks, timers and now the smoke alarm are good to go. Loved the extra hour of sleep too.
