Administration: Time Settings
Configuring System Time
To define system time:
STEP 1
The following fields are displayed:
• Actual Time (Static)—System time on the device. This shows the DHCP time zone or the acronym for
the user-defined time zone if these were defined.
• Last Synchronized Server—Address, stratum and type of the SNTP server from which system time
was last taken.
STEP 2
Clock Source Settings—Select the source used to set the system clock.
• Main Clock Source (SNTP Servers)—If this is enabled, the system time is obtained from an SNTP
server. To use this feature, you must also configure a connection to an SNTP server in the SNTP
Interface Settings page. Optionally, enforce authentication of the SNTP sessions by using the SNTP
Authentication page.
• Alternate Clock Source (PC via active HTTP/HTTPS sessions)—Select to set the date and time
from the configuring computer using the HTTP protocol.
The Clock Source Setting needs to be set to either of the above in order for RIP MD5
NOTE
authentication to work.
Manual Settings—Set the date and time manually. The local time is used when there is no alternate source
of time, such as an SNTP server:
• Date—Enter the system date.
• Local Time—Enter the system time.
Time Zone Settings—The local time is used via the DHCP server or Time Zone offset.
• Get Time Zone from DHCP—Select to enable dynamic configuration of the time zone and the DST
from the DHCP server. Whether one or both of these parameters can be configured depends on the
information found in the DHCP packet. If this option is enabled, DHCP client must be enabled on the
device.
The DHCP Client supports Option 100 providing dynamic time zone setting.
NOTE
• Time Zone from DHCP—Displays the acronym of the time zone configured from the DHCP server.
This acronym appears in the Actual Time field
• Time Zone Offset—Select the difference in hours between Greenwich Mean Time (GMT) and the
local time. For example, the Time Zone Offset for Paris is GMT +1, while the Time Zone Offset for New
York is GMT – 5.
