# 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
# convention, but are not legally binding national borders.... 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.
# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
# Before 1920, all ships kept local apparent time on the high seas by setting
# their clocks at night or at the morning sight so that, given the ship's
# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
# meridian (12 o'clock = local apparent noon). During 1917, at the
# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
# ships, both military and civilian, should adopt hourly standard time zones
# on the high seas. Whenever a ship was within the territorial waters of any
# nation it would use that nation's standard time. The captain was permitted
# to change his ship's clocks at a time of his choice following his ship's
# entry into another zone time--he often chose midnight. These zones were
# adopted by all major fleets between 1920 and 1925 but not by many
# independent merchant ships until World War II.
