Goal

In this document we discuss about the Timezone on the ZFS Storage Appliance (ZFSSA)

In a geographically distributed environment, an administrator may need to check the date/time on the storage when reviewing reported events in Maintenance Logs :

Alerts
Faults
System
Audit
Phone Home

Also it may be required to check the time during performance analysis in Analytics Dataset.

Solution

Administrator may check need to check the time using the BUI or CLI.

CLI

It will always report the time in UTC ( GMT + 0 )

For example : If you check the date on CLI :

maintenance logs alert> date
2014-3-27 10:55:41 <<<< This is UTC

maintenance logs alert> show

entry-099 2014-3-20 23:26:12 74a7674b-62e2-ca83-d3d0-d11017a647db, The appliance has rejoined the cluster., Minor alert

BUI

It will report the time same as the the local system on which browser is opened.

So for example if your timezone is GMT+5:30 then for the same alert you will notice different time which will be as per local timezone.

So BUI will report maintenance logs alert as below :

2014-3-21 04:56:12 74a7674b-62e2-ca83-d3d0-d11017a647db The appliance has rejoined the cluster. Minor alert

Similarly while checking Analytics and you will see the time on the dataset graph in your local timezone.

While reporting an issue to Oracle Support it will be useful if you specifically mention the time of issue in UTC as the logs in support bundle will also report time in UTC.
