Configuring Date/Time Groups


Use Date/Time Groups to define time zones for the various devices connected to Cisco CallManager. Each device is a member of only one device pool, and each device pool is assigned only one Date/Time Group.

A default Date/Time Group called CMLocal is configured automatically when you install Cisco CallManager. CMLocal is synchronized to the active date and time of the operating system on the server where Cisco CallManager is installed. After installing Cisco CallManager, you can change the settings for CMLocal as desired. Normally, server date/time should be adjusted to the local time zone date and time.


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



Tips For a worldwide distribution of Cisco IP Phones, create one named Date/Time Group for each of the 24 time zones.


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

Adding a Date/Time Group

This section describes how to add a new Date/Time Group to the Cisco CallManager database.

Procedure


Step 1 Open Cisco CallManager Administration.

Step 2 Select System > Date/Time Group.

Step 3 There are two ways to add a new Date/Time group:

If there is an existing Date/Time Group with settings that are similar to the new group you want to create, select the existing group to display its settings, click Copy, then continue with the Step 4 and modify the settings as needed.

To create a new Date/Time Group without copying an existing one, continue with Step 4.

Step 4 In the Date/Time Group Name field, enter the name you want to assign to the new Date/Time Group.

Step 5 From the Time Zone drop-down list box, select the time zone for the group you are adding. The option "local time zone of CallManager" copies the time zone information from the operating system of the server where Cisco CallManager is installed.

Step 6 Select the separator character to use between the date fields from the drop-down list box.

Step 7 From the Date Format drop-down list box, select the date format. This selection sets the format for the date displayed on the Cisco IP Phones.

Step 8 From the Time Format drop-down list box, select 12-hour or 24-hour time.

Step 9 Click Insert to save the new Date/Time Group in the database.

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:

Updating a Date/Time Group

This section describes how to update a Date/Time Group.

Procedure


Step 1 Open Cisco CallManager Administration.

Step 2 Select System > Date/Time Group.

Step 3 From the Date/Time Group list, select the Date/Time Group you want to update.

Step 4 Make the desired changes in the fields you want to update. Refer to the "Adding a Date/Time Group" section for more information about configuration settings. Before saving the changes, you can click Cancel to reset all fields to their original value.

Step 5 Click Update to save the changes in the database.


Tips The Restart Devices button restarts all devices in the selected Date/Time Group. This button is only for your convenience in restarting devices. You do not have to use it when making changes to a Date/Time Group.

This section describes how to delete a Date/Time Group from the Cisco CallManager database.

Before You Begin

You cannot delete a Date/Time Group that is used by any device pool. If you try to delete a Date/Time Group that is in use, Cisco 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 are using the Date/Time Group you want to delete. See the "Updating a Device Pool" section.

Delete the device pools that are using the Date/Time Group you want to delete. See the "Deleting a Device Pool" section.

Procedure


Step 1 Open Cisco CallManager Administration.

Step 2 Select System > Date/Time Group.

Step 3 From the Date/Time Group list, select the Date/Time Group you want to delete.

Step 4 Click Delete.

Step 5 When asked to confirm the delete operation, click either OK to delete or Cancel to cancel the delete operation.
