The storage system 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 operating system include date and time. Time is commonly expressed in UTC, a modern continuation of GMT, or local time with an offset from UTC.
Configure the "Timezone" field by first identifying the time zone identifier. Enter the command to list available time zone settings: cli% setdate -tzlist If UTC is to be set, then use the following command: cli% setdate -tz Etc/UTC
Verify the "Timezone" field is configured by entering the following command: cli% showdate Node Date 0 2016-05-18 23:46:29 UTC (Etc/UTC) 1 2016-05-18 23:46:37 UTC (Etc/UTC) If the output does not match the required time zone, this is a finding.
