Is anyone having problems with the timekeeping of their Pure Chronos? The time keeps shifting back an hour. I first noticed it a few days ago. In the evening, at 00:25, the clock was showing 23:25, but by the morning it had corrected itself. This morning, the alarm was an hour late

, and the clock was once again an hour slow.
Chronos appears to set its time off the DAB signal, but I don't know which part of the signal contains the information - eg whether the station selected would affect the time received. I'll have a fiddle round, but has anyone else experienced this? Found a solution?
