1. A method comprising:

  • receiving, by a network device, one or more advertisement messages comprising timing information describing a quality of a network clock that is originated by a master clock device at a root of a directed acyclic graph (DAG);

    the network device executing an objective function for the DAG providing an optimized loopless time topology for the network clock, synchronized to the master clock device, based on the timing information; and

    the network device attaching to a parent device in the DAG based on the objective function, for optimized generation of the network clock by the network device.
