July 24, 2008 10 Digital Broadcaster User Manual v. 3.4 rev. 3421

Configuring the Time Zone and NTP Time Servers

Set the Time Zone so your broadcast schedule is in sync as expected. Set your NTP server so

your Digital Broadcaster maintains highly accurate time sync. The Digital Broadcaster must

be able to send and receive traffic on UDP Port 123 on your network for NTP support.

1. In Webmin, click on Hardware  System Time to reach the System Time

configuration page.

2. Fill in the time zone and time server fields.

• Change Timezone To – Select your time zone from the pull-down menu and click

the Save button. This will cause services including web servers and database servers

to reset, so you many lose connection to the application momentarily.

• Primary Trusted Timeserver hostname or address – Select a timeserver to

synchronize the time on your server. You may use a local timeserver on your network

or a public timeserver on the Internet. If using a public NTP server, pick one that is

close to your location, such as in your state. If DNS has been enabled at your

installation (you entered a DNS server name on the Edit Bootup Interface page) enter

the hostname in the form name.domain.gTLD. Otherwise use the timeserver’s IP

address in the form nnn.nnn.nnn.nnn.

Note: At this time, one place to find IP addresses of timeservers around the

world is http://ntp.isc.org/bin/view/Servers/StratumTwoTimeServers. Look for

a timeserver with an open access policy. If you are in an area that uses

Daylight Saving Time, make sure the timeserver is in an area with DST also.

• Secondary Trusted Timeserver hostname or address – Enter the hostname or IP

address of a different NTP timeserver to act as a backup. If you used a local

timeserver as your primary, you might want to use a public timeserver here.

Note: Some installations block access to DNS or NTP for security purposes.

Your server, not just your workstation, must have access to a timeserver. You

might need to enter the IP address of your internal timeserver, rather than its

hostname. If you have difficulty accessing a timeserver, contact your IT staff.
