Document Type and Number:
WIPO Patent Application WO/2020/135857
Kind Code:
A1
Abstract:
Disclosed are a time synchronization method, system and device, and a storage medium. The time synchronization method comprises: a clock master device sending, to a clock slave device, a first time message carrying a first timestamp, wherein the first time message carries the first timestamp recorded by the clock master device when the first time message exits from a port of the clock master device; the clock master device receiving a second time message that is sent by the clock slave device and carries a second timestamp and a third timestamp, and putting, in the second time message, a fourth timestamp recorded by the clock master device when the second time message enters from the port of the clock master device, wherein the second timestamp is used for indicating the moment when the clock slave device receives the first time message, and the third timestamp is used for indicating the moment when the clock slave device sends the second time message; and the clock master device copying the second time message to generate a third time message, and sending the third time message to the clock slave device.
