Set Date and Time

➢ To configure Date & Time settings:
1. If not already logged in, log in to Device Administration to get admin access (see Log in to Device Administration).
2. Under ‘Device admin settings’, scroll down and tap Date & Time.
3. Adjust according to your preferences.
➢ Configuring time zones on Teams devices
● AudioCodes recommends using Geolocation (the default setting) as the time zone configuration method.

With Geolocation, if no other changes to the time zone settings are made, the device retrieves the time from its geographical location.

● Manual time zone setting is NOT recommended. Choosing a time zone manually may cause retrieval of the incorrect time zone, and cause functionality issues.

You can configure the time zone using one of the following methods, which are listed in order of preference for best performance:

■ Geolocation (Default):
● The default geolocation method uses a device’s public IP address to obtain its location. If the devices are behind NAT, they use a STUN server to discover their public IP addresses.
● A common STUN server example is Google's publicly accessible server: stun.l.google.com:19302 (default URL).
■ DHCP Option 100/101 (posix/tzdbx):
● Configuration is obtained from DHCP server (once defined as available).
■ Admin Provisioning:

Use one of the following:

● Teams Admin Center, created under configuration profile. For details refer to the relevant Microsoft documentation.
● Device Manager, created in configuration parameters setup.

The following parameters are available for time setup:

● /date_time/time_dst – enable or disable daylight saving time validation (see below).
● /date_time/time_format and /date_time/date_format – set date and time display format.
● /date_time/timezone_id, /date_time/timezone, /date_time/time_zone_retrieval_mechanism, /date_time/time_zone_region – automate time zone retrieval or set up the time zone.
