+# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
+# How Tonga became `The Land where Time Begins'
+# </a>:
+
+# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
+# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
+# standard time in 1940s, Tonga had the choice of subtracting from its
+# local time to come on the same standard time as New Zealand or of
+# advancing its time to maintain the differential of 13 degrees
+# (approximately 50 minutes ahead of New Zealand time).
+#
+# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
+# Tungi, preferred to ensure Tonga's title as the land where time
+# begins, the Legislative Assembly approved the latter change.
+#
+# But some of the older, more conservative members from the outer
+# islands objected. "If at midnight on Dec. 31, we move ahead 40
+# minutes, as your Royal Highness wishes, what becomes of the 40
+# minutes we have lost?"
+#
+# The Crown Prince, presented an unanswerable argument: "Remember that
+# on the World Day of Prayer, you would be the first people on Earth
+# to say your prayers in the morning."

+
+# The International Date Line
+
+# From Gwillim Law (2000-01-03):
+#
+# The International Date Line is not defined by any international standard,
+# convention, or treaty. Mapmakers are free to draw it as they please.
+# Reputable mapmakers will simply ensure that every point of land appears on
+# the correct side of the IDL, according to the date legally observed there.
+#
+# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
+# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
+# to the east side of the Phoenix and Line Islands), I suppose that most
+# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
+# has a rather arbitrary nature. The straight-line boundaries between Pacific
+# island nations that are shown on many maps are based on an international
+# convention, but are not legally binding national borders.
+#
+# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
+# legal time on the high seas would be zone time, i.e., the standard time at
+# the nearest meridian that is a multiple of fifteen degrees. The date is
+# governed by the IDL; therefore, even on the high seas, there may be some
+# places as late as fourteen hours later than UTC. And, since the IDL is not
+# an international standard, there are some places on the high seas where the
+# correct date is ambiguous.
