Windows Time Client
NTP4 Query Command Line ToolThe NTP4 Query Command Line Tool allows you to troubleshoot and benchmark the performance of the NTP4 Plug-In. This tool is included free with PresenTense Client. To view all available commands, type "help". To view the current synchronization status of your computer, type "peer" - this will display important information about each remote accurate time source. Some important parameters are documented below :
reach - a positive value indicates if PresenTense Time Client has been able to communicate with this server.
offset - this value denotes the current clock offset to the accurate time source in milliseconds.
jitter - this value denotes the variance in server response times.
Please note that it is normal for the NTP4 Plug-In to observe your system clock drift for several minutes before making its first system time adjustment.
