Abstract: A clock synchronization method, including: obtaining (S201), by a slave clock apparatus, a first time point at which a master clock apparatus sends first information, a second time point at which the slave clock apparatus receives the first information from the master clock apparatus, a third time point at which the slave clock apparatus sends first feedback information, and a fourth time point at which the master clock apparatus receives the first feedback information from the slave clock apparatus; then obtaining (S202) a first clock count offset based on the first time point, the second time point, the third time point, and the fourth time point; then obtaining (S206) a first clock frequency offset based on the first clock count offset; and finally adjusting (S207) a clock count step of the slave clock apparatus based on the first clock frequency offset.
