>From <https://en.wikipedia.org/wiki/British_Summer_Time>:
A further inquiry during 1966–1967 led the government of Harold
Wilson to introduce the British Standard Time experiment, with
Britain remaining on GMT+1 throughout the year. This took place
between 27 October 1968 and 31 October 1971, when there was a
reversion to the previous arrangement.
