How to get milliseconds when substructing datetime objects?

[Dmitri O.Kondratiev]

Please help to find simple solutiion for measuring times of operations with
millisecond precision.
For this I am trying to use datetime() objects:

import time
import datetime

def dreamTime(secs):
    t1 = datetime.datetime.now()
    time.sleep(secs)
    t2 = datetime.datetime.now()
    dt = t2 - t1
    print "Start time: "+str(t1)
    print "Stop  time: "+str(t2)
    print "Dream time sec: "+str(dt)
    """
    # The following code results in errors like:
    # AttributeError: 'datetime.timedelta' object has no attribute 'second'
    """
    dts = dt.second
    dtmicro = dt.microsecond
    dtmilli = dts * 1000 + dtmicro / float(1000)
    dts2 = dtmilli / float(1000)
    print "Dream Millies: "+str(dtmilli)
    print "Dream Seconds, again: "+str(dts2)

Thanks!
