# From Paul Eggert (2014-10-30):

#
# I guessed that time zone abbreviations through 1945 followed the same

#
# The 1906 transition was effective July 1 and standardized Indochina to
# Phù Liễn Observatory, legally 104 deg. 17'17" east of Paris.
# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
# the Paris Meridian (2 deg. 20'14.03" E); the former yields 07:06:30.1333...
# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
# which is used below even though the modern-day Phù Liễn Observatory
# is closer to 07:06:31. Abbreviate Phù Liễn Mean Time as PLMT.
#
# The following transitions occurred in Indochina in general (before 1954)
# and in South Vietnam in particular (after 1954):
# To 07:00 on 1911-05-01.
