Editing System Date And Time Settings - Dell PowerVault Storage Area Network Administrator's Manual

NOTE: System synchronization is critical for proper data archiving and replication service operations.
By using the NTP mode, you synchronize your system clock whereby NTP ensures that your system has a reliable time
stamp. This is critical for successful file exchanges, network log coordination and validation, and resource access
requests within a workgroup.
NOTE: Dell recommends that you use the NTP mode to ensure better replication service operations when part of a
workgroup. You can set or modify existing date and time settings for your DR Series system by using the Edit option
in the Date and Time page. However, the NTP service is disabled when you join a domain, at which point the
domain time management is used and you cannot enable NTP.

Editing System Date and Time Settings

To modify the default time and date settings for your DR Series system, complete the following:
1. Select System Configuration → Date and Time.
The Date and Time page is displayed.
2. Click Edit on the options bar.
The Edit Date and Time dialog is displayed.
NOTE: If the DR Series system is joined to a Microsoft Active Directory Services (ADS) domain, the Edit option
will be disabled (grayed out) and the Mode, Time Zone, or Date and Time values cannot be changed in the
Settings pane. This is because whenever a DR Series system is joined to a domain, the Network Time Protocol
(NTP) is disabled and the DR Series system uses the domain-based time service. NTP is used in the Mode
setting when the DR Series system is part of a workgroup and not joined to a domain. To be able to modify or
edit any of the Settings pane values when the DR Series system is joined to an ADS domain, you would first
need to leave the ADS domain before you could modify any of the date and time settings. For more
information, see
