| 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 AIX 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. |
