A network device includes one or more ports coupled to a network, a path determination module, and a clock synchronization module. The one or more ports receive a plurality of time synchronization packets from a master clock device. The path determination module identifies, based on respective path information included in each of at least some of the plurality of time synchronization packets, particular communication paths among two or more communication paths between the master clock device and the network device, via which the respective time synchronization packets traveled from the master clock device to the network device. The clock module determines a system time clock based on respective time information included in the at least some of the plurality of time synchronization packets and the identifications of the particular communication paths via which the respective time synchronization packets traveled from the master clock device to the network device.
