The present invention discloses a method and a system for correcting a time when an Optical Transport Network (OTN) bears a time synchronization protocol, which are used for solving the technical problem that the time synchronization protocol cannot be transported normally because of the unfixed transport delay time of the OTN network. In the present invention, when time synchronization protocol data are added in and dropped off the OTN network, a delay time during which the data passes through the OTN network is calculated based on an accurate synchronization time inside the OTN network, and the delay time is written in a correction filed of the time synchronization protocol data packet, thereby correcting the influence on the time synchronization protocol caused by the unfixed delay time in the OTN network. |
