Use of timedelta is incorrect about pystalkd

[menezes-]

timedelta.total_seconds was also added on python 3.2+ so i will update the code to use the following function:

def total_seconds(td):
    """
    simulates the total_seconds function added in python 3.2+ and 2.7+
    See 
    :param td: timedelta
    :type td: timedelta
    :return: float representing total seconds from timedelta
    :rtype: float
    """
    return (td.microseconds + (td.seconds + td.days * 24 * 3600) * 10 ** 6) / 10 ** 6
