I can also tell you something odd about a dab clock radio. Every
so often it jumps back an hour for no apparent reason.

and the PIPs are not synchronised with those on FM.

Yes, the time taken to process the original analogue input and convert
to digital means that digital radio and TV transmissions run a little
behind the real world.

More to the point the conversion back to analogue takes varying lengths
of time depending on the receiver. So digital outputs aren't even
synchronised with each other.
