In SQL Standard you set a client timezone using SET TIME ZONE, which
PostgreSQL supports.

Timezone can be set using the "timezone" configuration parameter,
which can be set in the file postgresql.conf, or in any of the other
standard ways described, such as set for each session using SET. There
are also some special ways to set it:

* The SQL command SET TIME ZONE sets the time zone for the session.

* The PGTZ environment variable is used by libpq clients to send a
SET TIME ZONE command to the server upon connection.

So you can set this on the client or the server, for the user,
explicitly and other ways.
