Methods and systems for performing time synchronization for a Cellular Vehicle-to-Everything (C-VX) wireless interface of a vehicle are provided. In one example, a method comprises: determining, by a vehicle UE, whether a Global Navigation Satellite System (GNSS) receiver of the vehicle receives a GNSS signal including time information for a time synchronization operation for the vehicle's local clock source; based on whether the GNSS receiver receives a GNSS signal including the time information, adjusting a local clock time of the vehicle's local clock source based on one of: the time information included in the GNSS signal, or one or more wireless signals broadcasted from a base station; and adjusting, based on the adjusted local clock time, at least one of: a phase or a frequency of a clock signal supplied to the C-VX wireless interface.
