Table 3-8. System Date and Time Settings
Setting Description (or Subfield and Description)
System Date and Time
From the pull-down menu, select an NTP server, or select to enter the time manually.
Use Default NTP Servers The STM’s real-time clock (RTC), which it uses for scheduling, is updated
regularly by contacting a default NETGEAR NTP server on the Internet.
This is the default setting.
Use Custom NTP Servers The STM’s RTC is updated regularly by contacting one of the two NTP
servers (primary and backup), both of which you must specify in the fields
that become available with this menu selection.
Note: If you select this option but leave either the Server 1 or Server 2 field
blank, both fields are automatically set to the default NETGEAR NTP
servers.
Note: A list of public NTP servers is available at
http://ntp.isc.org/bin/view/Servers/WebHome.
Server 1 Name /
IP Address
Enter the IP address or host name the primary NTP
server.
Server 2 Name /
IP Address
Enter the IP address or host name the secondary NTP
server.
Manually Enter the Date
and Time
Date Enter the date in the yyyy-mm-dd (year-month-date)
format.
Time Enter the time in the hh-mm-ss (hour-minutes-seconds)
format.
Time Zone
From the pull-down menu, select the local time zone in which the STM operates. The proper time zone
is required in order for scheduling to work correctly. You do not need to configure daylight savings time,
which is applied automatically when applicable. Greenwich Mean Time (GMT) is the default setting.
Note: When you select a time zone that is not associated with a location such as
“(GMT -08:00) GMT-8“, daylight savings time is automatically disabled. When you select a time zone
that is associated with a location such as “(GMT -08:00) Pacific Time ( US & Canada)”, daylight savings
time is automatically enabled.
Note: If you select the default NTP servers or if you enter a custom server FQDN, the
STM determines the IP address of the NTP server by performing a DNS lookup.
You must configure a DNS server address in the Network menu before the STM
can perform this lookup.
