High precision system time in python

Question

Is there a way to get high precision system time in python?

I have a small application for working with a virtual COM port. I want to measure the time interval between sending a message and receiving it.

Currently it works as follows:

I get a message, use

    time.time()

and add 20 messages to the message. The client application receives this message and receives

    time.time()

then calculates their differences. In most cases, the time interval (as expected) is zero.

Question: is there a way to do this more intelligently and with greater accuracy?
