A new file 'backzone' contains data which may appeal to
connoisseurs of old time stamps, although it is out of scope for
the tz database and is often poorly sourced. The new file is not
recommended for ordinary use and its entries are not installed by
default. (Thanks to Lester Caine for the Guernsey, Jersey, and
Isle of Man entries in 'backzone'.)

# 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 (2014-08-12):
# 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 were questionable and/or they
# differed from other zones only in pre-1970 time stamps.
# Unless otherwise specified, the source for the data is the following,
# which does not itself cite sources and is often wrong:
#
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
# San Diego: ACS Publications, Inc. (2003).
# This file is not intended to be compiled standalone, as it
# assumes rules from other files. In the tz distribution, use
# 'make posix_packrat' to compile 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.

# Isle of Man

# From Lester Caine (2013-09-04):
# The Isle of Man legislation is now on-line at
# <http://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 uncertinity as to the starting date
# of the first summer time in 1916 which may have be announced a
# couple of days late. There is still a substatial number of
# documents to work through, but it is thought that every GB change
# was also implemented on the island.
