Date Time Groups#

Overview#

Date Time Groups define time zones for the various devices that are connected to CUCM. Each device exists as a member of only one device pool, and each device pool has only one assigned Date Time Group.

CUCM automatically configures a default Date Time Group, called CMLocal, which syncs to the active date and time of the operating system on the server where CUCM is installed. You can change the settings for CMLocal, as required. 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.
