Abstract :
In order to improve the time synchronization precision to insure the communication timely, several types of clock synchronization methods were compared, analyzed the IEEE1588 clock synchronization system, discussed the PTP system software programming, introduced some source code transplanting methods, got the root cause of the low precision, provided three major improving methods, tested the improved system, the results indicate the high precision time synchronization has been attained.
