Abstract
A method for transmitting synchronization messages in a communications network including a plurality of nodes having a first node and at least one second node, wherein in order to take into account differences in a reference clock frequency of a reference clock and an internal clock frequency of an internal clock of the at least one second node, a compensation interval, with which the second clock count state is adjusted on measurement of a delay time, is subdivided into smaller compensation timespans, and the smaller compensation timespans are used to determine a compensated time value for the delay time with a high degree of accuracy, where the compensated time value is then used to update the time information in the synchronization message.
