Abstract
Technologies are described herein for time-synchronizing multiple remote network nodes concurrently with time beacons. A hub device in the network, at a preconfigured start time, begins to periodically broadcast time beacons containing current time values retrieved from an accurate time source over a beacon period, while other nodes of the network, at the same preconfigured start time, start listening for time beacons. When a node receives a time beacon broadcast by the hub device, the node sets a real-time clock of the node to the current time value in the received time beacon.
