Date/Time Group Configuration


Use Date/Time Groups to define time zones for the various devices that are connected to Cisco Unified CallManager. 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 CallManager 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 CallManager is installed. After installing Cisco Unified CallManager, 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 CallManager or upgrade the Cisco Unified CallManager 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 24 time zones.


Use the following topics to add, update, or delete Date/Time Groups:

Configuring a Date/Time Group

This section describes how to add, copy, or update a date/time group to the Cisco Unified CallManager database.

Procedure


Step 1 Choose System > Date/Time Group.

The Find and List Date/Time Groups window displays.

Step 2 Perform one of the following tasks:

To copy an existing date/time group, locate the appropriate date/time group as described in the "Finding a Date/Time Group" section, click the Copy button next to the date/time group that you want to copy, and continue with Step 3.

To add a new date/time group, locate the appropriate date/time group as described in the "Finding a Date/Time Group" section, click the Add New button, and continue with Step 3.

To update an existing date/time group, locate the appropriate date/time group as described in the "Finding a Date/Time Group" section and continue with Step 3.

Step 3 Enter the appropriate settings as described in Table 6-1.

Step 4 To get its date and time, a SIP phone can use NTP server(s) that exist in Cisco Unified CallManager Administration, as described in the "Phone NTP Reference Configuration" section on page 8-1. To add a phone NTP reference to a date/time group for a SIP phone, 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 "Finding the Phone NTP References" section on page 8-1.

Only phone NTP references that exist in the Cisco Unified CallManager database display. For information on adding a phone NTP reference to Cisco Unified CallManager Administration, see the "Configuring the Phone NTP References" section on page 8-2.

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 SIP phone 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 5 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 CallManager database.

Step 6 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).

Step 7 To reset the devices that use the date/time group, click Reset.


Next Steps

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, refer to the "Configuring a Device Pool" 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 CallManager database.

Deleting a Date/Time Group

This section describes how to delete a date/time group from the Cisco Unified CallManager database.

Before You Begin


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, refer to the "Accessing Dependency Records" section on page A-2.

If you attempt to delete a date/time group that is in use, Cisco Unified CallManager displays an error 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. Refer to the "Configuring a Device Pool" section.

Delete the device pools that use the date/time group that you want to delete. Refer to the "Deleting a Device Pool" section.

Procedure


Step 1 Find the date/time group by using the procedure in the "Finding a Date/Time Group" section.

Step 2 From the list of matching records, choose the date/time group that you want to delete.

Step 3 Click the Delete Selected Item icon that displays in the tool bar in the upper, left corner of the window (or click the Delete Selected button that displays at the bottom of the window) to delete the date/time group.

Step 4 When prompted to confirm the delete operation, click either OK to delete or Cancel to cancel the delete operation.
