1205 # In the past, some Kurdish nationalists, as a protest to the Iraqi

1207 # to daylight saving as Saddam time. But, as of today, the time zone

1511 # From Hideyuki Suzuki (1998-11-16):
1512 # The ordinance No. 51 (1886) established "standard time" in Japan,
1513 # which stands for the time on 135 degrees E.
1514 # In the ordinance No. 167 (1895), "standard time" was renamed to "central
1515 # standard time". And the same ordinance also established "western standard
1516 # time", which stands for the time on 120 degrees E.... But "western standard
1517 # time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
1518 # 167, there is no mention regarding for what place western standard time is
1519 # standard....
1520 #
1521 # I wrote "ordinance" above, but I don't know how to translate.
1522 # In Japanese it's "chokurei", which means ordinance from emperor.
1523
1524 # From Yu-Cheng Chuang (2013-07-12):
1525 # ...the Meiji Emperor announced Ordinance No. 167 of Meiji Year 28 "The clause
1526 # about standard time" ... The adoption began from Jan 1, 1896.

1202 # "The three northern provinces ... switched their clocks this spring and
1203 # are an hour ahead of Baghdad."
1204 #
1205 # But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
1206 # In the past, some Kurdish nationalists, as a protest to the Iraqi
1207 # Government, did not adhere to daylight saving time. They referred
1208 # to daylight saving as Saddam time. But, as of today, the time zone
1209 # in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.

2792 # From Paul Eggert (2014-07-15):
2793 # Time in Saudi Arabia and other countries in the Arabian peninsula was not
2794 # standardized until relatively recently; we don't know when, and possibly it
3110 # From Paul Eggert (2014-10-04):
3111 # Milne gives 7:16:56 for the meridian of Saigon in 1899, as being
3112 # used in Lower Laos, Cambodia, and Annam. But this is quite a ways
3113 # from Saigon's location. For now, ignore this and stick with Shanks
3114 # and Pottenger for LMT before 1906.
3115
3116 # From Arthur David Olson (2008-03-18):
3117 # The English-language name of Vietnam's most populous city is "Ho Chi Minh
3118 # City"; use Ho_Chi_Minh below to avoid a name of more than 14 characters.

3120 # From Paul Eggert (2014-10-21) after a heads-up from Trần Ngọc Quân:
3121 # Trần Tiến Bình's authoritative book "Lịch Việt Nam: thế kỷ XX-XXI (1901-2100)"
3122 # (Nhà xuất bản Văn Hoá - Thông Tin, Hanoi, 2005), pp 49-50,
3123 # is quoted verbatim in:

3125 # is translated by Brian Inglis in:
3126 # https://mm.icann.org/pipermail/tz/2014-October/021654.html
3127 # and is the basis for the information below.
3128 #
3129 # The 1906 transition was effective July 1 and standardized Indochina to
3130 # Phù Liễn Observatory, legally 104° 17' 17" east of Paris.
3131 # It's unclear whether this meant legal Paris Mean Time (00:09:21) or
3132 # the Paris Meridian (2° 20' 14.03" E); the former yields 07:06:30.1333...
3133 # and the latter 07:06:29.333... so either way it rounds to 07:06:30,
3134 # which is used below even though the modern-day Phù Liễn Observatory
3135 # is closer to 07:06:31. Abbreviate Phù Liễn Mean Time as PLMT.
3136 #
3137 # The following transitions occurred in Indochina in general (before 1954)
3138 # and in South Vietnam in particular (after 1954):
3139 # To 07:00 on 1911-05-01.
3140 # To 08:00 on 1942-12-31 at 23:00.
3141 # To 09:00 in 1945-03-14 at 23:00.
3142 # To 07:00 on 1945-09-02 in Vietnam.
3143 # To 08:00 on 1947-04-01 in French-controlled Indochina.
3144 # To 07:00 on 1955-07-01 in South Vietnam.
3145 # To 08:00 on 1959-12-31 at 23:00 in South Vietnam.
3146 # To 07:00 on 1975-06-13 in South Vietnam.
