Configuring System Date and Time Settings
If you need to configure or manage the date and time settings used by your system that synchronize it with other DR
Series systems or clients running in your domain, navigate to the Date and Time page, and click Edit. The Date and Time
page displays a Settings pane that contains the following date and time-related settings (by default, the system has the
following date and time settings as default values in an initial system startup):
• Mode—select from two types: Manual and Network Time Protocol (NTP).
NOTE: Dell recommends using NTP when the DR Series system is part of a workgroup and not part of a
domain. When the DR Series system is joined to a domain, such as the Microsoft Active Directory Services
(ADS) domain, NTP is disabled and the DR Series system uses the domain time.
• Time Zone—when in NTP mode, select from a list of time zone options based on Greenwich Mean Time (GMT); for
example, GMT-8:00, Pacific Time (US and Canada).
• NTP Servers—when in NTP mode, select from an Internet pool of NTP servers (you can define up to three NTP
servers) when using the NTP mode. If this setting is not visible in the Settings pane, verify that the Mode indicates it
is joined to an Active Directory Services (ADS) domain. When joined to a domain, NTP is disabled for the DR Series
system.
• Set Date and Time—when in Manual mode, click the calendar icon, and configure the date and time by making
month, day, and time in a 24-hour time format selections. Use the controls on the calendar to select the month, the
day of the month, and the hours and minutes using the slider controls. To set the current time, click Now. When done
with setting your date and time values, click Done (and the time appears for example, as 12/12/12 14:05:45). When all
date and time settings are configured, click Submit for the DR Series system to accept the new values.
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.
