Anyone any insight into this error? Yesterday , coincidently? the
longest day. Set the alarm function for 06:30. Luckily woke just after
06:00 and decided to get up . Synchronous mains clock read 06:08 but
radio-code clock read 04:08, minute and seconds agreeing with another
radio-code clock but it had decided to go east 2 time zones. Still
like that about 07:00 but on returning in the evening the erroneous
clock had reset itself. How to predict when this error will reoccur?
any amelioration, plenty of LCD contrast so presumably the batteries
are ok?

I have a clock that has been off by 1 or 2 hours a couple of times. I just
figured that it made a mistake interpreting the received signal, perhaps due to
interference. It has corrected by the next day each time.
