Discussion

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).

Check Content

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.

Fix Text

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();"
