time not properly parsed in auth_token middleware throws exception

[Nicholas Mistry]

on debian squeeze the time format returned is %Y-%m-%dT%H:%M:%S.%f-%z and the extra time zone offset information causes get_datetime to throw an exception, in the file keystone/middleware/auth_token.py. specifically the line ms = int(microseconds.ljust(6, '0')[:6])

def get_datetime(time_string):
    """ Gets datetime object with microsecond accuracy from input string.
    Handle strings which don't include microseconds

    :param: time_string: datetime in %Y-%m-%dT%H:%M:%S.%f format (.%f optional)
    """
    result = time_string.split(".", 1)
    datetime_string = result[0]
    microseconds = result[1] if len(result) > 1 else "0"
    d1 = datetime.strptime(datetime_string, "%Y-%m-%dT%H:%M:%S")
    ms = int(microseconds.ljust(6, '0')[:6])
    return d1.replace(microsecond=ms)
