| 1384 | +# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): |
| 1385 | +# Before 1920, all ships kept local apparent time on the high seas by setting |
| 1386 | +# their clocks at night or at the morning sight so that, given the ship's |
| 1387 | +# speed and direction, it would be 12 o'clock when the Sun crossed the ship's |
| 1388 | +# meridian (12 o'clock = local apparent noon). During 1917, at the |
| 1389 | +# Anglo-French Conference on Time-keeping at Sea, it was recommended that all |
| 1390 | +# ships, both military and civilian, should adopt hourly standard time zones |
| 1391 | +# on the high seas. Whenever a ship was within the territorial waters of any |
| 1392 | +# nation it would use that nation's standard time. The captain was permitted |
| 1393 | +# to change his ship's clocks at a time of his choice following his ship's |
| 1394 | +# entry into another zone time--he often chose midnight. These zones were |
| 1395 | +# adopted by all major fleets between 1920 and 1925 but not by many |
| 1396 | +# independent merchant ships until World War II. |
