Abstract
The present invention disclose a clock synchronization method. By the operations of: receiving a plurality of data packets sent by a host and acquiring receiving time when each data packet is received and a sending interval at which each two adjacent data packets are sent, wherein each data packet comprises a packet sequence and a first packet timestamp when the first data packet is sent; carrying out screening processing on all data packets according to the sending interval and the receiving time and packet sequence of each data packet so as to obtain at least one valid data packet; obtaining a time compensation value according to the receiving time and packet sequence of each valid data packet, the first packet timestamp, and the sending interval; and adjusting time of a slave according to the time compensation value so as to realize clock synchronization between the slave and the host.
