tznames
|
|
=======
|
|
|
|
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.
|
|
|
|
The files named Africa.txt, etc, are not intended to be used directly as
|
|
time zone abbreviation files. They contain reference definitions of time zone
|
|
names that can be copied into a custom abbreviation file as needed.
|
|
|
|
Note that these files (*.txt) are already a subset of the zic timezone
|
|
database files: we tried to list only those time zones that (according to
|
|
the zic timezone database) appear to be still in use.
