Abstract: Apparatus, methods, and computer-readable media for facilitating time synchronization functionality at user equipment are disclosed herein. An example method for wireless communication at a first device includes transmitting, to a second device, capability information indicating that the first device is capable of operating as a PTP grand master clock. The example method also includes receiving, from the second device, one or more PTP parameters based on the capability information indicating that the first device is capable of operating as a PTP grand master clock. Additionally, the example method includes generating, based on the one or more PTP parameters received from the second device, a first PTP message including time information. Further, the example method includes transmitting the first PTP message including the time information to one or more downstream devices in communication with the first device.
