After "import time", time.time() returns the time (elapsed since an
arbitrary epoch) with the unit of measure being the second, but the
precision being as high as the platform on which you're running will
allow.  The difference between two results of calling time.time() is
therefore in seconds _and fractions_; whether the precision is (e.g.)
1/100 of a second, or 1/1000 of a second, or whatever, depends on
what platform you're running.  In any case, just multiply that difference
by 1000 and you'll have it in milliseconds (possibly rounded e.g. to the
closest 10 milliseconds if you underlying platform doesn't provide
better precision than that, of course).
