Its surprising the VW's don't have this feature. Vauxhalls for one have had radio controlled clocks for a long time, I believe they use the RDS radio data to determine the correct time 
interesting.... i've never seen this feature applied to car clocks until now, then again i haven't owned many cars, not really have talked much about clock accuracy to people on the topic of cars, it's probably like many other people, how big the engine is, turbo/supercharged etc etc
it doesn't sound that expensive to install either, if you can get a clock from Argos that's radio controlled for £20 or something, surely the circuitry could be integrated to car electronics easily?
or perhaps it is not that easy, maybe it's super difficult and that's why not all cars have it?
