1. A method performed by a user-plane function (UPF) in a wireless communication system, the method comprising:
measuring a time offset between a 5th generation system (5GS) time and a time-sensitive networking (TSN) time;
transmitting, to a session management function (SMF), a report message including information regarding the time offset between the 5GS time and the TSN time; and
receiving, from the SMF, a report ack message,
wherein the time offset is used for a mapping of a burst arrival time from a TSN clock to a 5G clock in the SMF, and
wherein the transmitting of the report message including information regarding the time offset between the 5GS time and the TSN time comprises:
identifying whether a change to the time offset between the 5GS time and the TSN time from a previous time offset between a TSN time and a 5GS time is larger than a threshold, and
transmitting, to the SMF, the report message including information regarding the time offset between the 5GS time and the TSN time, in case that the change is larger than the threshold.
