...........and according to Bill Gates we are still one hour ahead of GMT (GMT+1hour),
I thought GMT is history, the correct is UTC (except on my QSL-cards)

That might be it. Some time ago a local electricity company sold quite a lot
of economy seven electric storage heaters to people in this village. After a
little while we started getting frequent outages in the small hours of the
morning. This was of course in the middle of winter. It seems the bulk of
the people who bought the heaters were all on the same phase of our
three-phase overhead distribution. So, at 2 o'clock in the morning, that
phase was suddenly overloaded and the overcurrent protection operated.

I understand that control rooms for both electricity and water companies
have precise details of when commercial television advertisements are
scheduled to be transmitted, as well the actual times when episodes of
popular programmes finish.
