A Bridge obtains UTC time from a 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. The devices then synchronize their time displayed to the received UTC time and 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. When required, a Bridge can be set to receive time from specific NTP Servers.
Go to Devices > Bridges.
