Any real pedant would know that in the vicinity of the zero meridian
we stopped using GMT - based on astronomical time in 1972 and switched
(after failing to agree the defining language for its TLA with the
French) to UTC - based on atomic time.

"We" does not include the UK, where legal time remains GMT-based, use of
UTC time-signals notwithstanding.

Presumably, therefore, you live in France, Spain (UTC-based, I think),
Algeria, Mali, Burkina Faso, Ghana, or Togo. Or afloat. Or in Sanae.

BTW, UTC is based on astronomical time; that is what Leap Seconds are
for. Only the scale of seconds is atomic-based.

The correct TLAs for the times of almost all of the UK are GMT and BST.

How, in general, does UK transport deal with services operating across
and around 01:00 GMT on the last Sunday of March and of October?
