CHAPTER 5: Configuration

• Time Zone: Sets the time zone, relative to Greenwich Mean Time. Note that

the Time Zone setting will function differently, depending on whether or not the

NTP feature is enabled and properly conﬁgured. (Default = GMT (No DST).)



NTP Enabled: The Time Zone setting is used to adjust the Greenwich

Mean Time value (received from the NTP server) to determine the precise

local time for the selected time zone.



NTP Disabled: If NTP is disabled, or if the Secure Site Manager is not

able to access the NTP server, then status screens and activity logs will list

the selected Time Zone and current Real Time Clock value, but will not

apply the correction factor to the displayed Real Time Clock value.

• NTP Enable: When enabled, the Secure Site Manager will contact an NTP

server (deﬁned via the NTP IP Address prompts) once a day, and update its

clock based on the NTP server time and selected Time Zone. (Default = Off.)

Notes:

• The Secure Site Manager will also contact the NTP server and

update the time whenever you change NTP parameters.

• To command the Secure Site Manager to immediately contact

the NTP server at any time, make certain that the NTP feature is

enabled and configured, then type /F and press [Enter]. When

the System Parameters menu appears, press [Esc]. The Secure

Site Manager will save parameters and then attempt to contact

the server, as specified by currently defined NTP parameters.

• Primary NTP IP Address: Deﬁnes the IP address for the primary NTP server.

(Default = undeﬁned.)

• Secondary NTP IP Address: Deﬁnes the IP address for the secondary, fallback

NTP Server. (Default = undeﬁned.)

• NTP Timeout: The amount of time in seconds, that will elapse between each

attempt to contact the NTP server. When the initial attempt is unsuccessful, the

Secure Site Manager will retry the connection four times. If neither the primary

nor secondary NTP server responds, the Secure Site Manager will wait 24 hours

before attempting to contact the NTP server again. (Default = 3 Seconds.)
