The F5 BIG-IP appliance must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC).
Severity | Group ID | Group Title | Version | Rule ID | Date | STIG Version |

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 application include date and time. Time is commonly expressed in UTC, a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC.
ℹ️ Check
From the BIG-IP GUI:
1. System.
2. Platform.
3. Verify that "UTC" is configured for "Time Zone".
From the BIG-IP Console, issue the following commands:
tmsh list sys ntp timezone
Note: This must return a value of "UTC".
If the BIG-IP appliance is not configured for the UTC time zone, this is a finding.
✔️ Fix
From the BIG-IP GUI:
1. System.
2. Platform.
3. Set "UTC" for "Time Zone".
4. Click "Update".
From the BIG-IP Console, issue the following commands:
tmsh modify sys ntp timezone UTC
tmsh save sys config
