Date/Time Group Configuration Settings

In Cisco Unified Communications Manager Administration, use the System > Date/Time Group menu path to configure date/time groups.

Use Date/Time Groups to define time zones for the various devices that are connected to Cisco Unified Communications Manager. Each device exists as a member of only one device pool, and each device pool has only one assigned Date/Time Group.

Installing Cisco Unified Communications Manager automatically configures a default Date/Time Group that is called CMLocal. CMLocal synchronizes to the active date and time of the operating system on the server where Cisco Unified Communications Manager is installed. After installing Cisco Unified Communications Manager, you can change the settings for CMLocal as desired. Normally, adjust server date/time to the local time zone date and time.


Note CMLocal resets to the operating system date and time whenever you restart Cisco Unified Communications Manager or upgrade the Cisco Unified Communications Manager software to a new release. Do not change the name of CMLocal.

Tip For a worldwide distribution of Cisco Unified IP Phones, create one named Date/Time Group for each of the time zones in which you will deploy endpoints.

Additional Configuration for Date/Time Groups

Use the following procedure to add a phone NTP reference to a date/time group for a phone that is running SIP.

Procedure


Step 1 To get its date and time, a phone that is running SIP can use NTP server(s) that exist in Cisco Unified Communications Manager Administration, as described in the "Phone NTP Reference Configuration" section. To add a phone NTP reference to a date/time group for a phone that is running SIP, perform the following tasks:

a. Click the Add Phone NTP References button.

b. Find the phone NTP reference(s) that you want to add, as described in the "Phone NTP Reference Configuration Settings" section.

Only phone NTP references that exist in the Cisco Unified Communications Manager database display. For information on adding a phone NTP reference to Cisco Unified Communications Manager Administration, see the "Phone NTP Reference Configuration Settings" section.

c. After the search results display, check the check boxes for any phone NTP references that you want to add to the date/time group or click Select All.

d. Click Add Selected.


Tip After you add the phone NTP reference(s) to the date/time group, you can prioritize them, starting with the first server that you want the phone that is running SIP to contact. For example, to move a server to the top of the list, highlight the entry in the pane and click the Up arrow. To move a server to the bottom of the list, highlight the entry in the pane and click the Down arrow.

Step 2 To remove a phone NTP reference from the date/time group, highlight the reference in the pane and click Remove Phone NTP References.

Removing the phone NTP reference from the date/time group does not remove the phone NTP reference from the Cisco Unified Communications Manager database.

Step 3 To save the new date/time group in the database, click the Save icon that displays in the tool bar in the upper, left corner of the window (or click the Save button that displays at the bottom of the window).


Note See the procedure described in "Synchronizing a Date/Time Group With Affected Devices" section before deciding on whether to proceed to Step 4.

Step 4 To reset the devices that use the date/time group, click Reset.


After adding a new date/time group to the database, you can assign it to a device pool to configure the date and time information for that device pool. For more information, see the "Device Pool Configuration Settings" section.

Tips About Deleting Date/Time Groups


Note You cannot delete a date/time group that any device pool uses.

To find out which device pools use the date/time group, choose Dependency Records from the Related Links drop-down list box on the Date/Time Group Configuration window and click Go.

If the dependency records feature is not enabled for the system, the dependency records summary window displays a message that shows the action that you can take to enable the dependency records; the message also displays information about high CPU consumption that is related to the dependency records feature. For more information about dependency records, see the "Accessing Dependency Records" section.

If you attempt to delete a date/time group that is in use, Cisco Unified Communications Manager displays a message. Before deleting a date/time group that is currently in use, you must perform either or both of the following tasks:

Assign a different date/time group to any device pools that use the date/time group that you want to delete. See the "Device Pool Configuration Settings" section.

Delete the device pools that use the date/time group that you want to delete. See the "Tips About Deleting Device Pools" section.

Using the GUI

For instructions on how to use the Cisco Unified Communications Manager Administration Graphical User Interface (GUI) to find, delete, configure, or copy records, see the "Navigating the Cisco Unified Communications Manager Administration Application" section and its subsections, which explain how to use the GUI and detail the functions of the buttons and icons.

Configuration Settings Table

Table 6-1 describes the date/time group configuration settings. For related procedures, see the "Related Topics" section.

Table 6-1 Date/Time Group Configuration Settings 

Field
Description

Group Name

Enter the name that you want to assign to the new date/time group.

Time Zone

From the drop-down list box, choose the time zone for the group that you are adding.

The default setting for new Cisco Unified Communications Manager installations equals (GMT) Monrovia, Casablanca.

If you upgrade from a compatible Cisco Unified Communications Manager release and you use "local time zone of Communications Manager" in the configuration, the Cisco Unified Communications Manager database determines the appropriate time zone for the database server and then displays that time zone as replacement for the Communications Manager time zone.

Separator

Choose the separator character to use between the date fields.

Date Format

Choose the date format for the date that displays on the Cisco Unified IP Phones.

Time Format

Choose a 12-hour or 24-hour time format.

Selected Phone NTP References (ordered by highest priority)

To ensure that a phone that is running SIP gets its date and time configuration from an NTP server, add the phone NTP reference(s) to the date/time group. To add a phone NTP reference to the date/time group, perform the following tasks:

1. Click the Add Phone NTP References button.

2. Find the phone NTP reference(s) that you want to add, as described in the "Phone NTP Reference Configuration Settings" section.

Only phone NTP references that exist in the Cisco Unified Communications Manager database display. For information on adding a phone NTP reference to Cisco Unified Communications Manager Administration, see the "Tips About Configuring Phone NTP References" section.

3. After the search results display, check the check boxes for the phone NTP references or click Select All.

4. Click Add Selected.

After you add the phone NTP reference(s) to the date/time group, you can prioritize them, starting with the first reference that you want the phone to contact. For example, to move a reference to the top of the list, highlight the entry in the pane and click the Up arrow. To move a reference to the bottom of the list, highlight the entry in the pane and click the Down arrow.

Tip To remove a phone NTP reference from the date/time group, highlight the server in the pane and click Remove Phone NTP References. Removing the phone NTP reference from the date/time group does not remove the phone NTP reference from the Cisco Unified Communications Manager database.

Synchronizing a Date/Time Group With Affected Devices

To synchronize devices to a date/time group that has undergone configuration changes, perform the following procedure, which applies any outstanding configuration settings in the least-intrusive manner possible. (For example, a reset/restart may not be required on some affected devices.)

Procedure


Step 1 Choose System > Date/Time Group.

The Find and List Date/Time Groups window displays.

Step 2 Choose the search criteria to use.

Step 3 Click Find.

The window displays a list of Date/Time Groups that match the search criteria.

Step 4 Click the Date/Time Group to which you want to synchronize applicable devices. The Date/Time Group Configuration window displays.

Step 5 Make any additional configuration changes.

Step 6 Click Save.

Step 7 Click Apply Config.

The Apply Configuration Information dialog displays.

Step 8 Click OK.
