! # The ancients had no need for daylight saving, as they kept time
! # informally or via hours whose length depended on the time of year.
! # Daylight saving time in its modern sense was invented by the
! # New Zealand entomologist George Vernon Hudson (1867-1946),
! # whose day job as a postal clerk led him to value
! # after-hours daylight in which to pursue his research.
! # In 1895 he presented a paper to the Wellington Philosophical Society
! # that proposed a two-hour daylight-saving shift. See:
! # Hudson GV. On seasonal time-adjustment in countries south of lat. 30 deg.

! # http://rsnz.natlib.govt.nz/volume/rsnz_28/rsnz_28_00_006110.html
! # Although some interest was expressed in New Zealand, his proposal
! # did not find its way into law and eventually it was almost forgotten.

# subscription and open to the public. On the south face of the monolith,

# It is one of the paradoxes of history that we should owe the boon of

+ # From Vladimir in Moscow via Alois Treindl re Kiev time 1991/2 (2014-02-28):
+ # First in Ukraine they changed Time zone from UTC+3 to UTC+2 with DST:
+ # 03 25 1990 02:00 -03.00 1 Time Zone 3 with DST
+ # 07 01 1990 02:00 -02.00 1 Time Zone 2 with DST
+ # * Ukrainian Government's Resolution of 18.06.1990, No. 134.
+ # http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html
+ #
+ # They did not end DST in September, 1990 (according to the law,
+ # "summer time" was still in action):
+ # 09 30 1990 03:00 -02.00 1 Time Zone 2 with DST
+ # * Ukrainian Government's Resolution of 21.09.1990, No. 272.
+ # http://search.ligazakon.ua/l_doc2.nsf/link1/KP900272.html
+ #
+ # Again no change in March, 1991 ("summer time" in action):
+ # 03 31 1991 02:00 -02.00 1 Time Zone 2 with DST
+ #
+ # DST ended in September 1991 ("summer time" ended):
+ # 09 29 1991 03:00 -02.00 0 Time Zone 2, no DST
+ # * Ukrainian Government's Resolution of 25.09.1991, No. 225.
+ # http://www.uazakon.com/documents/date_21/pg_iwgdoc.htm
+ # This is an answer.
+ #
+ # Since 1992 they had normal DST procedure:
+ # 03 29 1992 02:00 -02.00 1 DST started
+ # 09 27 1992 03:00 -02.00 0 DST ended
