Change the Message Timestamp for IXXAT bus to a float value. Now, only an integer is calculated.

Possible solution:

Line 250:
self._tick_resolution = float(self._channel_capabilities.dwClockFreq / self._channel_capabilities.dwTscDivisor)

or

Line 358 of canlib.py in interfaces/ixxat change to
float(self._message.dwTime) / self._tick_resolution

Will that solution really work? If you first divide two integers you would still get an integer as a result. Casting the result to a float will not give you back the decimals. You should cast one of the values to a float to force Python to use a float division, like the second proposal.

Sorry, I was mistaken. That should work. Carry on... :)
