I've got a Boots radio controlled travel alarm clock, which was a Christmas present several years ago. It has interchangeable modules (referred to as "antennas" in the instructions, but they have several contacts suggesting more electronics inside) for time signals in use in different parts of the world (UK / USA / Japan West, Europe, Japan East). It will try to self-synchronise several times a day, at 01:00, 02:00, 03:00 (to be sure of catching a daylight saving change), 09:00, 15:00 and 21:00, but you can also force it to do so with a button press.

My cordless land line phones synchronise themselves to the timestamp from an incoming caller ID packet; so if a handset is fully discharged and then recharged, it will show a nonsense time from the moment it has enough juice in the battery to work again until someone rings.
