g u2212 v 1g itself small i e to perform fitting of the shape of the global time curve and dedicated local times g i as illustrated in fig4 a and 4 b and as described below the assumption for this embodiment is that v g can be influenced there are several different possibilities for this e g oscillators in which frequency is influenced by voltage hardware which can add or omit a pulse of the oscillator non integer conversion of a clock tick into counter values etc in addition according to the preceding discussion measurement of the offset is essentially a measurement of difference v g u2212 v 1g so the new value of v lg can be generated directly by using this difference in other words difference g i u2212 g may subsequently be distributed uniformly over an interval of length t another effect is cluster drift this means that due to the control of the global time using the global time thus determined cluster drift may occur in the form of a propagation of tolerance a quasi rise in the shape i e a drift of the total time of all users to be synchronized however with the method according to one embodiment the present invention it may be possible to prevent the entire cluster from drifting as a whole although well synchronized to one another this occurs for example by defining a maximum minimum value for correction of v 1g or by systematically influencing the correction of v 1g in the direction of the configuration values in other words instead of a theoretically ideal v 1g value a value slightly closer to the configuration value is used the details will always depend on the method by which v 1g is.
