Abstract
The disclosure describes methods and systems for performing time synchronization in a heterogeneous system. In one example, a method includes, for each secondary device of a plurality of secondary devices in a network: determining, by a computing system and based at least in part on a time indication for a clock on a master device and a time indication for a clock on a secondary device in the network, a time synchronization offset for the respective secondary device; collecting, from the respective secondary device, one or more static parameters and one or more dynamic parameters; determining, based on the one or more parameters, a weight to associate with the time synchronization offset for the respective secondary device; determining, based on each of the respective time synchronization offset for each of the plurality of secondary devices and the respective associated weight, a universal time synchronization offset for the network.
