15. A method performed by a clock system of a communication system, the method comprising:
tracking, by the clock system, time and generating a clock signal having a clock frequency;
receiving, by the clock system, a packet comprising a time reference from a master clock;
determining, by the clock system, an offset between the time reference and a time indicated by the clock system;
using, by the clock system, a feedback loop controller to determine a clock frequency adjustment for the clock system based on the offset;
applying, by the clock system, a smoothing filter to alter the clock frequency adjustment determined using the feedback loop controller; and
updating, by the clock system, the clock system using the altered clock frequency adjustment.
