# transition date for London, namely 1847 Sep 22. We don't know as much

# From Paul Eggert (1996-06-12):
|
||||
# Summer Time was first seriously proposed by William Willett (1857-1915),
|
||||
# a London builder who circulated a pamphlet ``Waste of Daylight'' (1907)
|
||||
# that proposed advancing clocks 20 minutes on each of four Sundays in April,
|
||||
# and retarding them by the same amount on four Sundays in September.
|
||||
# A bill was drafted in 1909 and introduced in Parliament several times,
|
||||
# but it met with ridicule and opposition, especially from farming interests.
|
||||
# One-hour Summer Time was eventually adopted as a wartime measure in 1916.

# No Order was passed, so 02:00 1971-10-31 it is...

# Interestingly, it says baldly `This Act shall come into force on
|

# 27 October 1968', without giving a time. As S1 of the Act merely

# stated that `The time for general purposes in the United Kingdom
