How to check timezone in PostgreSQL?

@mac 

To check the timezone setting in PostgreSQL, you can use the SHOW command with the timezone parameter:

1

SHOW timezone;

This will display the current timezone setting for the PostgreSQL server.

Alternatively, you can use the current_setting function to retrieve the value of the timezone configuration parameter:

1

SELECT current_setting('timezone');

Note that the timezone setting can also be specified at the session level, in which case it will override the server-level setting. You can check the session-level timezone setting using the session_timezone function:

1

SELECT session_timezone();

You can also set the timezone for a session using the SET command:

1

SET timezone TO 'America/New_York';

This will set the timezone for the current session to Eastern Standard Time (EST). You can use any valid timezone name recognized by PostgreSQL as the value for the timezone parameter.

Finally, you can also use the clock_timestamp function to retrieve the current timestamp in the current timezone:

1

SELECT clock_timestamp();

This will return the current timestamp in the timezone specified by the timezone configuration parameter. If a session-level timezone has been set, it will be used instead of the server-level timezone.

In PostgreSQL, you can check the current timezone using the following query:

1

SELECT current_setting('TIMEZONE') AS timezone;

This query will return the current timezone setting for the database.
