CUCM 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.

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.

Date/Time Group Configuration Settings

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 "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.

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.
