ntp in python

[Janto Dreijer]

I want to measure the packet delivery delays over various network
links. For this I need to synchronise the times of the sender and
receiver, either against NTP or eachother.

Unfortunately I won't necessarily have root priviledges to change the
PCs' clocks. So I'm looking for a way I can determine the offset and
simply correct my measurements from my Python code.

I doubt something like
http://www.nightsong.com/phr/python/setclock.py
would give me a resolution of less than 10ms - which is what I want.

Any Python module out there that uses a more sophisticated method?

btw I can do round-trip delivery and avoid the whole clock-mismatch
issue, but this would lose information on the network's asymmetry -
which would be really nice to have.
