VMware Postgres must use Coordinated Universal Time (UTC) for log timestamps.

If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by VMware Postgres must include date and time expressed in UTC, a modern continuation of Greenwich Mean Time (GMT).

At the command prompt, run the following command:

# /opt/vmware/vpostgres/current/bin/psql -U postgres -A -t -c "SHOW log_timezone;"

Expected result:

Etc/UTC

If the output does not match the expected result, this is a finding.

At the command prompt, run the following commands:

# /opt/vmware/vpostgres/current/bin/psql -U postgres -c "ALTER SYSTEM SET log_timezone TO 'Etc/UTC';"

# /opt/vmware/vpostgres/current/bin/psql -U postgres -c "SELECT pg_reload_conf();"
