# 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 th 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."
# From Paul Eggert (1999-08-12):
# Shanks says the transition was on 1968-10-01; go with Mundell.
# From Eric Ulevik (1999-05-03):
# Tonga's director of tourism, who is also secretary of the National Millenium
# Committee, has a plan to get Tonga back in front.
# He has proposed a one-off move to tropical daylight saving for Tonga from
# October to March, which has won approval in principle from the Tongan
# Government.
