# ...the European time rules are...standardized since 1981, when
|
|
# most European counrties started DST. Before that year, only
|
|
# a few countries (UK, France, Italy) had DST, each according
|
|
# to own national rules. In 1981, however, DST started on
|
|
# 'Apr firstSun', and not on 'Mar lastSun' as in the following
|
|
# years...
|
|
# But also since 1981 there are some more national exceptions
|
|
# than listed in 'europe': Switzerland, for example, joined DST
|
|
# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
|
|
# lastSun' in 1981---I don't know how they handle now.
|
|
#
|
|
# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
|
|
# Soviet Union (as far as I know).

#
|
|
# The information from Tom Hofmann is (as far as I know) not entirely correct.
|
|
# After a request from chongo at amdahl I tried to retrieve all information
|
|
# about DST in Europe. I was able to find all from about 1969.
|
|
#
|
|
# ...standardization
|
|
# on DST in Europe started in about 1977 with switches on first Sunday in
|
|
# April and last Sunday in September. In UK it was from last but 1 Sunday
|
|
# in march to last Sunday in October. In 1981 UK joined Europe insofar that
|
|
# the starting day for both shifted to last Sunday in March. And from 1982
|
|
# the whole of Europe used DST, with switch dates April 1 and October 1 in
|
|
# the Sovjet Union. In 1985 the SU reverted to standard Europen switch
|
|
# dates. Note that currently in the UK the switch back date appears not
|
|
# to be the last Sunday in October, but 4 weeks after the last Sunday in
|
|
# September (withness 1982 and 1983 with terminating days October 24 and 23).
|
|
#
|
|
# It should also be remembered that time-zones are not constants; e.g.
|
|
# Portugal switched in 1976 from MET (or CET) to WET with DST, and the UK
|
|
# used MET throughout from 1967 to 1969, and WET with DST before and after
|
|
# that time. Note also that though there were rules for switch dates not
|
|
# all countries abided to these dates, and many individual deviations
|
|
# occurred, though not since 1982 I believe. Another note: it is always
|
|
# assumed that DST is 1 hour ahead of normal time, this need not be the
|
|
# case; at least in the Netherlands there have been times when DST was 2 hours
|
|
# in advance of normal time.
