    My prognosis, is the latter !

    BTW 'Green Zone' ?! What happened to volts as a measurement of battery health ?

    Inn many cases, dumbing down to suit users and save the maker a penyn or
    two on the manufacture.

    If it's an analogue meter, they save the cost of calibrating and
    printing a scale, if it's a warning light, above the acceptable voltage,
    oyu get green, otherwise you get a red light.

    Normally the radio controlled clocks with a analogue display seem to
    update quite quickly i.e. they do not seem to wait for an overnight signal.

    Some move to midnight first and wait for a signal.

    It just came to a standstill at around 3 am but started again when I
    removed and reinserted the battery. It is still running happily and
    showing the correct time.

    Is it DCF77 clock or whatever they call MSF now? MSF had maintenance
    period when no signal but DCF77 just switches to the reserve transmitter.

    Its MSF (Anthorn). I suppose maintenance could take place during the
    night but would this cause the clock to stop? I assumed it would keep
    running independently and re-link to the time signal when it returned.
    Maybe it stops every night at 3 am and resets before I wake up :-)

    Just done a reset on a couple of MSF clocks, will see if they find a signal.

    Thanks.

    Both my MSF clocks have synchronised OK.
