A method, a device and a system for clock synchronization are provided. The method includes: under a first transfer mode, generating a first receiving timestamp by using a first link, and acquiring a first transmitting timestamp of a master clock device; under a second transfer mode, generating a second transmitting timestamp by using the first link, and acquiring a second receiving timestamp of the master clock device; and acquiring a time difference to the master clock device according to the first receiving timestamp, the first transmitting timestamp, the second transmitting timestamp and the second receiving timestamp, and realizing a clock synchronization with the master clock device by using the time difference. A slave clock device and a master clock device are provided in the embodiments of the present invention, as well as a system for clock synchronization. |
