Синтаксис#

SET TIME ZONE LOCAL
SET TIME ZONE expression

Sets the default time zone for the current session.

If the LOCAL option is specified, the time zone for the current session is set to the initial time zone of the session.

If the expression option is specified:

if the type of the expression is a string, the time zone for the current session is set to the corresponding region-based time zone ID or the corresponding zone offset.
if the type of the expression is an interval, the time zone for the current session is set to the corresponding zone offset relative to UTC. It must be in the range of [-14,14] hours.

Use the default time zone for the current session:

SET TIME ZONE LOCAL;

Use a zone offset for specifying the time zone:

SET TIME ZONE '-08:00';

Use an interval literal for specifying the time zone:

SET TIME ZONE INTERVAL '10' HOUR;
SET TIME ZONE INTERVAL -'08:00' HOUR TO MINUTE;

Use a region-based time zone identifier for specifying the time zone:

SET TIME ZONE 'America/Los_Angeles';

The time zone identifier to be used can be passed as the output of a function call:

SET TIME ZONE concat_ws('/', 'America', 'Los_Angeles');

Setting the default time zone for the session has no effect if the sql.forced-session-time-zone configuration property is already set.
