get_result() always returns an error if timeout < 1000

[JanBeelte]

Issues

I believe we are doing integer division which is why we can only specify multiples of full seconds.
In that way defining a timeout parameter as milliseconds integer is very confusing.

I think this is where we are doing an integer division by mistake:

Proposed solutions

Use datetime.timedelta type for the timeout, use datetime.datetime type (datetime.now() ) for end_time calculation.

If you want I could raise a PR with the respective changes.
