# Zones that go back beyond the scope of the tz database

# This file is in the public domain.

# This file is by no means authoritative; if you think you know
# better, go ahead and edit it (and please send any changes to
# tz@iana.org for general use in the future).  For more, please see
# the file CONTRIBUTING in the tz distribution.


# From Paul Eggert (2014-10-31):

# This file contains data outside the normal scope of the tz database,
# in that its zones do not differ from normal tz zones after 1970.
# Links in this file point to zones in this file, superseding links in
# the file 'backward'.

# Although zones in this file may be of some use for analyzing
# pre-1970 time stamps, they are less reliable, cover only a tiny
# sliver of the pre-1970 era, and cannot feasibly be improved to cover
# most of the era.  Because the zones are out of normal scope for the
# database, less effort is put into maintaining this file.  Many of
# the zones were formerly in other source files, but were removed or
# replaced by links as their data entries were questionable and/or they
# differed from other zones only in pre-1970 time stamps.

# Unless otherwise specified, the source for data through 1990 is:
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
# San Diego: ACS Publications, Inc. (2003).
# Unfortunately this book contains many errors and cites no sources.

# This file is not intended to be compiled standalone, as it
# assumes rules from other files.  In the tz distribution, use
# 'make PACKRATDATA=backzone zones' to compile and install this file.

# Zones are sorted by zone name.  Each zone is preceded by the
# name of the country that the zone is in, along with any other
# commentary and rules associated with the entry.
#
# As explained in the zic man page, the zone columns are:
# Zone	NAME		GMTOFF	RULES	FORMAT	[UNTIL]

# Ethiopia
# From Paul Eggert (2014-07-31):
# Like the Swahili of Kenya and Tanzania, many Ethiopians keep a
# 12-hour clock starting at our 06:00, so their "8 o'clock" is our
# 02:00 or 14:00.  Keep this in mind when you ask the time in Amharic.
#
# Shanks & Pottenger write that Ethiopia had six narrowly-spaced time
# zones between 1870 and 1890, that they merged to 38E50 (2:35:20) in
# 1890, and that they switched to 3:00 on 1936-05-05.  Perhaps 38E50
# was for Adis Dera.  Quite likely the Shanks data entries are wrong
# anyway.

# Cambodia
# From Paul Eggert (2014-10-11):
# See Asia/Ho_Chi_Minh for the source for most of this data.  Also, guess
# (1) Cambodia reverted to UT +07 on 1945-09-02, when Vietnam did, and
# (2) they also reverted to +07 on 1953-11-09, the date of independence.
# These guesses are probably wrong but they're better than guessing no
# transitions there.

# Isle of Man
#
# From Lester Caine (2013-09-04):
# The Isle of Man legislation is now on-line at
# <https://www.legislation.gov.im>, starting with the original Statutory
# Time Act in 1883 and including additional confirmation of some of
# the dates of the 'Summer Time' orders originating at
# Westminster.  There is a little uncertainty as to the starting date
# of the first summer time in 1916 which may have been announced a
# couple of days late.  There is still a substantial number of
# documents to work through, but it is thought that every GB change
# was also implemented on the island.
