摘要：
A method, apparatus, and computer implemented instructions for synchronizing time in a network data processing system. A request for time synchronization is received at a target data processing system. A current target time at the target data processing system is placed in a reply. The reply is sent to the source data processing system. A current source time from when the reply is received at the source data processing system is compared to the current target time to generate a comparison. A synchronization factor is generated using the comparison.
