The Content Analysis System (CAS) must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT).

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 application include date and time. Time is commonly expressed in UTC, a modern continuation of GMT, or local time with an offset from UTC.

Verify the time zone is set to "UTC" with the following steps:

1. Log on to the SSH CLI with an administrative account. 2. Enter "show timezone current". 3. Review the output for the current system time zone setting.

If "Timezone" does not state "UTC", this is a finding.

Configure the time zone to "UTC" with the following steps:

1. Log on to the SSH CLI with an administrative account. 2. Enter "enable" and provide the password. 3. Enter "configure terminal". 4. Set the system time zone by entering "timezone UTC". 5. Enter "exit" to return to the config context, and then enter "exit" again to leave configuration mode.
