System Time
The System Time section allows the administrator to set the time (hh:mm:ss), date (mm:dd:yyyy) and time
zone. It also allows the administrator to select automatic synchronization with the NTP (Network Time Protocol)
server and to display UTC (Coordinated Universal Time) instead of local time in logs.
NTP Settings
The NTP Settings section allows the administrator to set an update interval (in seconds), an NTP server, and two
additional (optional) NTP servers.
Setting the Time
To configure the time and date settings, navigate to the System > Time page. The appliance uses the time and
date settings to timestamp log events and for other internal purposes. It is imperative that the system time be
set accurately for optimal performance and proper registration.
To configure the time and date settings:
1 Select your time zone in the Time Zone drop-down list.
2 The current time, in 24-hour time format, appears in the Time (hh:mm:ss) field and the current date
appears in the Date (mm:dd:yyyy) field.
3 Alternately, you can manually enter the current time in the Time (hh:mm:ss) field and the current date
in the Date (mm:dd:yyyy) field.
4Click Accept to update the configuration.
Enabling Network Time Protocol
If you enable Network Time Protocol (NTP), then the NTP time settings overrides the manually configured time
settings. The NTP time settings are determined by the NTP server and the time zone that is selected in the
Time Zone drop-down list.
To set the time and date for the appliance using the Network Time Protocol (NTP):
1 Navigate to the System > Time page.
2Select Automatically synchronize with an NTP server.
3 In the NTP Settings section, enter the time interval in seconds to synchronize time settings with the NTP
server in the Update Interval field. If no period is defined, the appliance selects the default update
interval, 3600 seconds.
4 Enter the NTP server IP address or fully qualified domain name (FQDN) in the NTP Server 1 field.
5 For redundancy, enter a backup NTP server address in the NTP Server Address 2 (Optional) and NTP
Server Address 3 (Optional) fields.
6Click Accept to update the configuration.
NOTE: For optimal performance, the SMA/SRA appliance must have the correct time and date configured.
NOTE: If the check box next to Automatically synchronize with an NTP server is selected,
you cannot manually enter the time and date. To manually enter the time and date, clear
the check box.
