 # Howse writes that the Netherlands' railways used GMT between 1892 and 1940,

-# The data before 1945 is taken from
+
+# However, Robert H. van Gent writes (2001-04-01):
+# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
+# Amsterdam mean time) onwards, the whole of the Netherlands (including
+# the Dutch railways) was required by law to observe Amsterdam mean time
+# (19 minutes 32.13 seconds ahead of GMT). This had already been the
+# common practice (except for the railways) for many decades but it was
+# not until 1909 when the Dutch government finally defined this by law.
+# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
+# was generally known as Dutch Time ("Nederlandse Tijd").
+#
+# (2001-04-08):
+# 1892-05-01 was the date when the Dutch railways were by law required to
+# observe GMT while the remainder of the Netherlands adhered to the common
+# practice of following Amsterdam mean time.
+#
+# (2001-04-09):
+# In 1835 the authorities of the province of North Holland requested the
+# municipal authorities of the towns and cities in the province to observe
+# Amsterdam mean time but I do not know in how many cases this request was
+# actually followed.
+#
+# From 1852 onwards the Dutch telegraph offices were by law required to
+# observe Amsterdam mean time. As the time signals from the observatory of
+# Leiden were also distributed by the telegraph system, I assume that most
+# places linked up with the telegraph (and railway) system automatically
+# adopted Amsterdam mean time.
+#
+# Although the early Dutch railway companies initially observed a variety
+# of times, most of them had adopted Amsterdam mean time by 1858 but it

 # Svalbard & Jan Mayen
+
+# From Steffen Thorsen (2001-05-01):
+# Although I could not find it explicitly, it seems that Jan Mayen and
+# Svalbard have been using the same time as Norway at least since the
+# time they were declared as parts of Norway.  Svalbard was declared
+# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
+# Mayen by law of 1930-02-27 no 2, section 2. (From
+# http://www.lovdata.no/all/nl-19250717-011.html and
+# http://www.lovdata.no/all/nl-19300227-002.html).  The law/regulation
+# for normal/standard time in Norway is from 1894-06-29 no 1 (came
+# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
+# part of this law since 1925/1930. (From
+# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been
+# able to find if Jan Mayen used a different time zone (e.g. -0100)
+# before 1930. Jan Mayen has only been "inhabitated" since 1921 by
+# Norwegian meteorologists and maybe used the same time as Norway ever
+# since 1921.  Svalbard (Arctic/Longyearbyen) has been inhabited since
+# before 1895, and therefore probably changed the local time somewhere
+# between 1895 and 1925 (inclusive).
+
+# From Paul Eggert (2001-05-01):
+#
+# Actually, Jan Mayen was never occupied by Germany during World War II,
+# so it must have diverged from Oslo time during the war, as Olso was
+# keeping Berlin time.
+#
+# <http://home.no.net/janmayen/history.htm> says that the meteorologists
+# burned down their station in 1940 and left the island, but returned in
+# 1941 with a small Norwegian garrison and continued operations despite
+# frequent air ttacks from Germans.  In 1943 the Americans established a
+# radiolocating station on the island, called "Atlantic City".  Possibly
+# the UTC offset changed during the war, but I think it unlikely that
+# Jan Mayen used German daylight-saving rules.
+#
+# Svalbard is more complicated, as it was raided in August 1941 by an
+# Allied party that evacuated the civilian population to England (says
+# <http://www.bartleby.com/65/sv/Svalbard.html>).  The Svalbard FAQ
+# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were

+# From Ivan Nilsson (2001-04-13), superseding Shanks:
+#
+# The law "Svensk forfattningssamling 1878, no 14" about standard time in 1879:
+# From the beginning of 1879 (that is 01-01 00:00) the time for all
+# places in the country is "the mean solar time for the meridian at
+# three degrees, or twelve minutes of time, to the west of the
+# meridian of the Observatory of Stockholm".  The law is dated 1878-05-31.
+#
+# The observatory at that time had the meridian 18 degrees 03' 30"
+# eastern longitude = 01:12:14 in time.  Less 12 minutes gives the
+# national standard time as 01:00:14 ahead of GMT....
+#
+# About the beginning of CET in Sweden. The lawtext ("Svensk
+# forfattningssamling 1899, no 44") states, that "from the beginning
+# of 1900... ... the same as the mean solar time for the meridian at
+# the distance of one hour of time from the meridian of the English
+# observatory at Greenwich, or at 12 minutes 14 seconds to the west
+# from the meridian of the Observatory of Stockholm". The law is dated
+# 1899-06-16.  In short: At 1900-01-01 00:00:00 the new standard time
+# in Sweden is 01:00:00 ahead of GMT.
+#
+# 1916: The lawtext ("Svensk forfattningssamling 1916, no 124") states
+# that "1916-05-15 is considered to begin one hour earlier". It is
+# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
+# Further the law says, that "1916-09-30 is considered to end one hour later".
+#
+# The laws regulating [DST] are available on the site of the Swedish
+# Parliament beginning with 1985 - the laws regulating 1980/1984 are

+#
+# (2001-05-13):

+# I have now found a newspaper stating that at 1916-10-01 01:00
+# summertime the church-clocks etc were set back one hour to show
+# 1916-10-01 00:00 standard time.  The article also reports that some
