+ Since timezone abbreviations are not well standardized,

+ the set of abbreviations accepted by the server. The
+ <xref linkend="guc-timezone-abbreviations"> run-time parameter
+ determines the active set of abbreviations. While this parameter
+ can be altered by any database user, the possible values for it
+ are under the control of the database administrator — they
+ are in fact names of configuration files stored in
+ <filename>.../share/timezonesets/</> of the installation directory.
+ By adding or altering files in that directory, the administrator
+ can set local policy for timezone abbreviations.
+ </para>
+
+ <para>
+ <literal>timezone_abbreviations</> can be set to any file name
+ found in <filename>.../share/timezonesets/</>, if the file's name
+ is entirely alphabetic. (The prohibition against non-alphabetic
+ characters in <literal>timezone_abbreviations</> prevents reading
+ files outside the intended directory, as well as reading editor
+ backup files and other extraneous files.)
+ </para>
+
+ <para>
+ A timezone abbreviation file may contain blank lines and comments
+ beginning with <literal>#</>. Non-comment lines must have one of
+ these formats:
+
+<synopsis>
+<replaceable>time_zone_name</replaceable> <replaceable>offset</replaceable>
+<replaceable>time_zone_name</replaceable> <replaceable>offset</replaceable> D
+@INCLUDE <replaceable>file_name</replaceable>
+@OVERRIDE
+</synopsis>
+ </para>
+
+ <para>
+ A <replaceable>time_zone_name</replaceable> is just the abbreviation
+ being defined. The <replaceable>offset</replaceable> is the zone's
+ offset in seconds from UTC, positive being east from Greenwich and
+ negative being west. For example, -18000 would be five hours west
+ of Greenwich, or North American east coast standard time. <literal>D</>
+ indicates that the zone name represents local daylight-savings time
+ rather than standard time.
+ </para>
+
+ <para>
+ The <literal>@INCLUDE</> syntax allows inclusion of another file in the
+ <filename>.../share/timezonesets/</> directory. Inclusion can be nested,
+ to a limited depth.
+ </para>
+
+ <para>
+ The <literal>@OVERRIDE</> syntax indicates that subsequent entries in the
+ file may override previous entries (i.e., entries obtained from included
+ files). Without this, conflicting definitions of the same timezone
+ abbreviation are considered an error.
+ </para>
+
+ <para>
+ In an unmodified installation, the file <filename>Default</> contains
+ all the non-conflicting time zone abbreviations for most of the world.
+ Additional files <filename>Australia</> and <filename>India</> are
+ provided for those regions: these files first include the
+ <literal>Default</> file and then add or modify timezones as needed.
+ </para>
+
+ <para>
+ For reference purposes, a standard installation also contains files
+ <filename>Africa.txt</>, <filename>America.txt</>, etc, containing
+ information about every time zone abbreviation known to be in use
+ according to the <literal>zic</> timezone database. The zone name
+ definitions found in these files can be copied and pasted into a custom
+ configuration file as needed. Note that these files cannot be directly
+ referenced as <literal>timezone_abbreviations</> settings, because of
+ the dot embedded in their names.
+ </para>
+
+ <caution>
+ <para>
+ Time zone abbreviations defined in the configuration file override
+ non-timezone meanings built into <productname>PostgreSQL</productname>.
+ For example, the <filename>Australia</> configuration file defines
+ <literal>SAT</> (for South Australian Standard Time). When this
+ file is active, <literal>SAT</> will not be recognized as an abbreviation
+ for Saturday.
+ </para>
+ </caution>
+
+ <caution>
+ <para>
+ If you modify files in <filename>.../share/timezonesets/</>,
+ it is up to you to make backups — a normal database dump
+ will not include this directory.

Since time zone rules change frequently in some parts of the world,
we should endeavor to update the data files before each PostgreSQL
release.
+
+At each update, we should check if time zone offsets have changed.
+Just search for the current or previous year and see what has changed.
+Sometimes a country changes its time zone offsets, for example Georgia
+in 2004. Just grepping in the zic database files for 2004 is enough to
+spot such a change. Then the files under tznames/ should be updated.

+This directory contains files with timezone sets for PostgreSQL. The problem
+is that time zone abbreviations are not unique throughout the world and you
+might find out that a time zone abbreviation in the `Default' set collides
+with the one you wanted to use. All other files except for `Default' are
+intended to override values from the `Default' set. So you might already have
+a file here that serves your needs. If not, you can create your own.
+
+In order to use one of these files, you need to set
+
+ timezone_abbreviations = 'xyz'
+
+in any of the usual ways for setting a parameter, where xyz is the filename
+that contains the desired time zone names.
+
+If you do not find an appropriate set of time zone names for your geographic
+location supplied here, please report this to <pgsql-hackers@postgresql.org>.
+Your set of time zone names can then be included in future releases.
+For the time being you can always add your own set.
