CHAPTER 12: SYSTEM MANAGEMENT
12.3 DATE AND TIME CONFIGURATION
Set the local Date and Time in your Black Box appliance as soon as it is configured. Features such as Syslog and NFS logging use
the system time for time-stamping log entries, while certificate generation depends on a correct Timestamp to check the validity
period of the certificate.
Your Black Box appliance can synchronize its system time with a remote Network Time Protocol (NTP) server. NTP uses
Coordinated Universal Time (UCT) for all time synchronizations so it is not affected by different time zones. You do need to specify
your local time zone so the system clock shows correct local time.
 Select System > Date & Time.
 Set your appropriate region in the Time Zone selection box and click Set Time.
NOTE: With firmware v3.2.0 and later the Time Zone can also be set to UTC, which replaced Greenwich Mean Time as the World
standard for time in 1986.
Configuring NTP ensures theBlack Box appliance clock is kept extremely accurate once an Internet connection has been
established.
 Select theEnable NTPcheckbox in theNetwork Time Protocol section of theSystem > Date & Timepage.
 Enter the IP address of the remoteNTP Server.
 If your external NTP server requires authentication, specify theNTP Authentication Keyand the Key Indexto use when
authenticating with the NTP server.

 ClickApply NTP Settings.
If remote NTP is not used, the time can be set manually:
 Enter theYear,Month,Day,HourandMinuteusing theDateandTimeselection boxes.
 CheckSet Time.
Black Box appliances have an internal, battery-backed hardware clock.Whether set manually, or set by an NTP server, thehardware
clock is automatically updated. The clock’sbattery maintains the time and date across reboots and when the appliance is powered
down.
