Clock synchronization deviation determination method and device, test equipment and storage medium

The embodiment of the invention provides a clock synchronization deviation determination method and device, test equipment and a storage medium, and relates to the technical field of clock synchronization. At least two groups of synchronous messages and subsequent messages sent by a master clock node are sequentially received, the arrival time of the at least two synchronous messages is recorded, and the at least two subsequent messages both carry the sending time of the same group of synchronous messages; according to the arrival time and the sending time of the at least two synchronous messages, determining whether the message sending time of the master clock node is stable or not; and under the condition that the time of sending the message by the master clock node is stable, receiving a synchronous message and a subsequent message sent by the slave clock node, determining the clock synchronization deviation of the slave clock node according to the synchronous message and the subsequent message sent by the
