UC Module

You can change the date and time settings used by the server through the server's web configuration pages. The System menu shows the server's current date and time.

By default the Unified Communications Module is set to use NTP with the NTP server address set to 169.254.0.1 (the IP Office system).

To change the server date and time settings:

1.Login to the server's web configuration menus.

2.Select Settings.

3.Select System.

4.Select the Date Time section.

Date
For a server not using NTP, this field shows the server's current date and allows that to be changed. If using NTP this field is greyed out.

Time
For a server not using NTP, this field shows the server's current UTC time and allows that to be changed. If using NTP this field is greyed out.

Timezone  
In some instances the time displayed or used by a function needs to be the local time rather than UTC time. The Timezone field determines the appropriate offset applied to the UTC time above. Note that changing the timezone can cause a "Session expired" message to appear in the browser in which case you need to login again.

Enable Network Time Protocol
When selected, the server obtains the current date and time from the NTP servers listed in the NTP Servers list below. It then uses that date and time and makes regular NTP requests for updates.

NTP Servers
With Enable Network Time Protocol selected, use this field to enter the IP address of an NTP server or servers to use. Enter each address as a separate line. The network administrator or ISP may have an NTP server for this purpose. A list of publicly accessible NTP servers is available at http://support.ntp.org/bin/view/Servers/WebHome. However, it is your responsibility to comply with the usage policy of the chosen server. Choose several unrelated NTP servers in case one of the servers becomes unreachable or its clock unreliable. The server uses the responses it receives from each NTP server to determine reliability.

The IP Office system can also use NTP to obtain its system time.

The default time setting for the Unified Communications Module is to use NTP with the server address set to 169.254.0.1 (the IP Office system). When this is set, you must configure the IP Office to get its time from an external SNTP server or set its time manually.

Synchronize system clock before starting service
Use this option to synchronize the system clock to an NTP time server before starting other services. Do not use this option if the time server cannot be reliably reached. Waiting for synchronization to occur may block use of the system until a timeout has passed.

Use local time source
When not selected, external NTP takes priority over the internal system clock. If selected, the local system clock is used as the time source. Only use this option if system clock is synchronized with another reliable source, for example a radio controlled clock device.

5.Click Save.
