+# 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.
