I've had a radio controlled alarm clock for a few years. A while ago it suddenly gained an hour and this morning my alarm went off and it turns out I had got up half n hour early, gained 30 mins 
Dunno if this down to the radio signal or just the clock is at fault.
If you've got a radio controlled clock, how reliable has it been for you?
