# Links and zones for backward compatibility

# This file is in the public domain, so clarified as of
# 2009-05-17 by Arthur David Olson.

# This file provides links from old or merged timezone names to current ones.
# It also provides a few zone entries for old naming conventions.
# Many names changed in 1993 and in 1995, and many merged names moved here
# in the period from 2013 through 2022.  Several of these names are
# also present in the file 'backzone', which has data important only
# for pre-1970 timestamps and so is out of scope for tzdb proper.

# Although this file is optional and tzdb will work if you omit it by
# building with 'make BACKWARD=', in practice downstream users
# typically use this file for backward compatibility.

# This file is divided into sections, one for each major reason for a
# backward compatibility link.  Each section is sorted by link name.

# A "#= TARGET1" comment labels each link inserted only because some
# .zi parsers (including tzcode through 2022e) mishandle links to links.
# The comment says what the target would be if these parsers were fixed
# so that data could contain links to links.  For example, the line
# "Link Australia/Sydney Australia/ACT #= Australia/Canberra" would be
# "Link Australia/Canberra Australia/ACT" were it not that data lines
# refrain from linking to links like Australia/Canberra, which means
# the Australia/ACT line links instead to Australia/Sydney,
# Australia/Canberra's target.
