Default Radio controlled clock an hour fast

Anyway, popped in today for the first time when passing, to see if they
had any interesting things in their deals. I picked up a new radio
controlled clock as our old one died.

Thing is, it's it sets itself an hour fast. Instructions say it uses the
DCF77 signal from Mainflingen in Germany, which presumably is giving
time in CET (GMT+1). Now I don't really know how the system works, but
the clocks obviously don't know where in the world they are so
presumably are set to pickup a specific signal.

I have a radio controlled watch, but on that I can set the time zone)

So are Lidl are selling a load of clocks which will set themselves wrong
:-)


Going off at a tangent...

Let us contemplate the idea that Scotland becomes independent, or
despite not being fully independent gained control over their time zone.
They then decide to shift their time zone differently to England and
Wales. But the MSF transmitter is in England.

Would there be vast numbers of radio-controlled clocks appearing on
eBay? With "Item located in Kirkcaldy, Dundee, Edinburgh, Aberdeen,
Glasgow, ..."

I can't think of a obvious technical solution unless the clocks are
switchable between time sources (as some are). Even then, the switch I
have seen is between existing sources - not some new fangled one on a
different frequency.
