Abstract
In various implementations, provided are techniques for distributing network time across a network using multiple grand masters (e.g., master time keepers). These techniques include having multiple grand masters simultaneously providing time to the network. Simultaneous means that all the grand masters are active at the same time, and none are designated as backups. In various implementations, the nodes in the network can simultaneously synchronize to network times provided by more than grand masters so that the nodes can obtain more than one network time. Using these multiple network times, nodes configured as clients can determine one network time. The client devices can then use the single network time in applications that require a time.
