Description
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 the DBMS must include date and time. Time is commonly expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC.

Check Text ( C-63020r938894_chk )
As the "enterprisedb" operating system user, run the following to show the current log_timezone setting: > psql -d edb -c "SHOW log_timezone" If anything other than "UTC" is returned, this is a finding.

Fix Text (F-62929r938895_fix)
As the "enterprisedb" operating system user, run the following to set the log_timezone parameter: > psql edb -c "ALTER SYSTEM SET log_timezone = 'UTC'" Next, reload the parameter file: psql edb -c "SELECT pg_reload_conf()" Confirm the new value: psql edb -c "SHOW log_timezone"
