Date/Time Group Configuration


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 24 time zones.


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

Finding a Date/Time Group

Because you might have several date/time groups in your network, Cisco Unified Communications Manager Administration lets you locate specific date/time groups on the basis of specific criteria. Use the following procedure to locate date/time groups.


Note During your work in a browser session, the cookies on the client machine store your find/list search preferences. If you navigate to other menu items and return to this menu item, or if you close the browser and then reopen a new browser window, your Cisco Unified Communications Manager search preferences get retained until you modify your search.


Procedure


Step 1 Choose System > Date/Time Group.

The Find and List Date/Time Groups window displays. Records from an active (prior) query may also display in the window.

Step 2 To find all records in the database, ensure the dialog box is empty; go to Step 3.

To filter or search records

From the first drop-down list box, select a search parameter.

From the second drop-down list box, select a search pattern.

Specify the appropriate search text, if applicable.


Note To add additional search criteria, click the + button. When you add criteria, the system searches for a record that matches all criteria that you specify. To remove criteria, click the - button to remove the last added criterion or click the Clear Filter button to remove all added search criteria.


Step 3 Click Find.

All matching records display. You can change the number of items that display on each page by choosing a different value from the Rows per Page drop-down list box.


Note You can delete multiple records from the database by checking the check boxes next to the appropriate record and clicking Delete Selected. You can delete all configurable records for this selection by clicking Select All and then clicking Delete Selected.


Step 4 From the list of records that display, click the link for the record that you want to view.


Note To reverse the sort order, click the up or down arrow, if available, in the list header.


The window displays the item that you choose.

Configuring a Date/Time Group

This section describes how to add, copy, or update a date/time group to the Cisco Unified Communications Manager 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, choose the date/time group that you want to copy, click the Copy icon that displays in the tool bar in the upper, left corner of the window (or the Copy button that displays at the bottom of the window), and continue with Step 3.

To add a new date/time group, 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 Communications Manager Administration, as described in the "Phone NTP Reference Configuration" section on page 5-1. 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 5-1.

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 "Configuring the Phone NTP References" section on page 5-2.

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 Communications Manager 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 on page 9-2.

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.

Deleting a Date/Time Group

This section describes how to delete a date/time group from the Cisco Unified Communications Manager 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 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. Refer to the "Configuring a Device Pool" section on page 9-2.

Delete the device pools that use the date/time group that you want to delete. Refer to the "Deleting a Device Pool" section on page 9-6.

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.
