A Bridge obtains UTC time from an NTP server during each check-in, and then sends the received UTC time to other Sync Bluetooth devices over its next connection to the Sync Bluetooth mesh network. When the devices connect to the mesh network, they synchronize the received UTC time to their assigned time zone.
By default, a Bridge's NTP Servers are set to Default. When set to Default, it connects to the NTP Servers set in the account profile.
