Abstract
A method and a first device (A) for synchronizing a first clock in the first device (A) with a second clock in a second device (B). The first device (A) estimates 5 (A) a relative clock phase offset, based on a sequence of round trip times, RTTs, of precision time protocol, PTP, messages which are exchanged between the first and second devices (A,B). The estimated relative clock phase offset is a time difference between a time of arrival of a first arrived PTP message among the PTP messages and a direct subsequent clock cycle. The first device (A) further determines 10 (A) a clock value of the first clock, based on the estimated relative clock phase offset, to synchronize the first clock with the second clock.
