DCF77 reception in Denmark degrades enormously due to all the fireworks

Euh... the signal is 77.5 KHz. Rather long waves. Have you measured this???
Yes.

Well, a little googling tells us that In Navy Cash, all dates and times are

Remember that I am somewhere around 1000km from the transmitter, there
isn't that much signal left when it comes here.
I'm not sure what the electromagnetic mechanism for the extincion is

In case you didn't notice -- this year Christmas falls on the

Some of the newcomers to the group may not be familiar

I'd be stunned if there were such a court case: a matter in which the
difference between GMT and UTC (or, indeed, any other 0.9s difference
in timescales) is going to be at issue is hard enough to construct as

They are actually across the river in Telehouse. They were part of a millennial
