# 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 timestamps, 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 timestamps.
|
|
|
|
# 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:

# 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.

|

# 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
