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 mesh network. The Sync bluetooth 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.
From the list, select the Gateway ID link of the bridge. The gateway profile of the bridge is displayed.
Select Show Advanced Options.
From the NTP Servers (1-3), enter the domain name for each NTP Server.
Its Update Pending status is set to Yes and the setting change is scheduled to be downloaded to the device during its next check-in to your OneVue account.
