The current algorithms are based on linear model, for example, Precision Time
Protocol (PTP) which requires frequent synchronization in order to handle the
effects of clock frequency drift. This paper introduces a nonlinear approach to
clock time synchronize. This approach can accurately model the frequency shift.
Therefore, the required time interval to synchronize clocks can be longer.
Meanwhile, it also offers better performance and relaxes the synchronization
process. The idea of the nonlinear algorithm and some numerical examples will
be presented in this paper in detail.
