Methods, systems, and computer readable media for distribution of time synchronization information to ultra-wide-band (UWB) devices are disclosed. A system includes anchors and tags having synchronized timing systems. The system includes a site master configured for transmitting a first time-synchronization message to at least a first anchor. The first anchor is configured for distributing time synchronization information to at least a second anchor by transmitting a first UWB message during an assigned time slot for the first anchor. The first UWB message includes timing information based on the first time-synchronization message.
