Fix Recommendation

Note: The following instructions use the PGDATA and PGVER environment variables. See supplementary content APPENDIX-F for instructions on configuring PGDATA and APPENDIX-H for PGVER.

To change log_timezone in postgresql.conf to use a different time zone for logs, as the database administrator (shown here as "postgres"), run the following: 

$ sudo su - postgres 
$ vi ${PGDATA?}/postgresql.conf 
log_timezone='UTC' 

Next, restart the database: 

# SYSTEMD SERVER ONLY 
$ sudo systemctl reload postgresql-${PGVER?}

# INITD SERVER ONLY 
$ sudo service postgresql-${PGVER?} reload

Note: The following instructions use the PGDATA environment variable. See supplementary content APPENDIX-F for instructions on configuring PGDATA.

When a PostgreSQL cluster is initialized using initdb, the PostgreSQL cluster will be configured to use the same time zone as the target server.

As the database administrator (shown here as "postgres"), check the current log_timezone setting by running the following SQL:

$ sudo su - postgres
$ psql -c "SHOW log_timezone"

log_timezone
--------------
UTC
(1 row)

If log_timezone is not set to the desired time zone, this is a finding.
