[ntp:questions] NTP Protocol Characterization

I am looking for a way to analyse NTP's performance under various
network conditions like jitter, latency, packet loss, misordering,
and so on.
I have two different ideas in mind:
- I have seen on ntp.org a reference to a tool called 'ntpdsim'.
However, I can't find this tool in the distribution. Then, this
lead to the other solution ....
- Using two PCs, each of them synchronized with GPS clock. Between
those PCs, I also run NTP through a network impairement generator
like PacketStorm. Then I compare the NTP-time with the GPS-time.
How can I compare my GPS-time and NTP-time? Is is possible to
have ntpd running without touching the system clock?
Thanks for your attention,
