68: # ...
69: #
70: # ...the European time rules are...standardized since 1981, when
71: # most European counrties started DST. Before that year, only
72: # a few countries (UK, France, Italy) had DST, each according
73: # to own national rules. In 1981, however, DST started on
74: # 'Apr firstSun', and not on 'Mar lastSun' as in the following
75: # years...
76: # But also since 1981 there are some more national exceptions
77: # than listed in 'europe': Switzerland, for example, joined DST
78: # one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
79: # lastSun' in 1981---I don't know how they handle now.
80: #
81: # Finally, DST ist always from 'Apr 1' to 'Oct 1' in the
82: # Soviet Union (as far as I know).

95: # Subject: timezones
96: # ...
97: #
98: # The information from Tom Hofmann is (as far as I know) not entirely correct.
99: # After a request from chongo at amdahl I tried to retrieve all information
100: # about DST in Europe. I was able to find all from about 1969.
101: #
102: # ...standardization
103: # on DST in Europe started in about 1977 with switches on first Sunday in
104: # April and last Sunday in September. In UK it was from last but 1 Sunday
105: # in march to last Sunday in October. In 1981 UK joined Europe insofar that
106: # the starting day for both shifted to last Sunday in March. And from 1982
107: # the whole of Europe used DST, with switch dates April 1 and October 1 in
108: # the Sovjet Union. In 1985 the SU reverted to standard Europen switch
109: # dates. Note that currently in the UK the switch back date appears not
110: # to be the last Sunday in October, but 4 weeks after the last Sunday in
111: # September (withness 1982 and 1983 with terminating days October 24 and 23).
112: #
113: # It should also be remembered that time-zones are not constants; e.g.
114: # Portugal switched in 1976 from MET (or CET) to WET with DST, and the UK
115: # used MET throughout from 1967 to 1969, and WET with DST before and after
116: # that time. Note also that though there were rules for switch dates not
117: # all countries abided to these dates, and many individual deviations
118: # occurred, though not since 1982 I believe. Another note: it is always
119: # assumed that DST is 1 hour ahead of normal time, this need not be the
120: # case; at least in the Netherlands there have been times when DST was 2 hours
121: # in advance of normal time.
