Configure Date Time Groups¶
Use Date Time Groups to define time zones for the various devices that are connected to Cisco Unified CM. Each device exists as a member of only one device pool, and each device pool has only one assigned Date Time Group.
Cisco Unified CM 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. You can change the settings for CMLocal as desired. Normally, adjust server Date and Time to the local time zone date and time.
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 deploy endpoints.
Perform these steps:
Log in as provider, reseller, or customer administrator.
Make sure that the hierarchy path is set to a customer or site level.
If prompted, select the NDL that contains the Cisco Unified CM on which you are configuring the Date Time Group.
Perform one of the following:
If you logged in as provider or reseller administrator, choose Device Management > CUCM > Date Time Groups.
If you logged in as a customer administrator, choose Device Management > Advanced > Date Time Groups.
Click Add.
