    Return the absolute time-distance string for two datetime objects,
    ints or any combination you can dream of.
    
    If times are integers, they are interpreted as seconds from now.
    
    ``granularity`` dictates where the string calculation is stopped.
    If set to seconds (default) you will receive the full string. If
    another accuracy is supplied you will receive an approximation.
    Available granularities are:
    'century', 'decade', 'year', 'month', 'day', 'hour', 'minute',
    'second'
    
    Setting ``round`` to true will increase the result by 1 if the fractional
    value is greater than 50% of the granularity unit.
    
    Examples:

    >>> distance_of_time_in_words(86399, round=True, granularity='day')
    '1 day'
    >>> distance_of_time_in_words(86399, granularity='day')
    'less than 1 day'
    >>> distance_of_time_in_words(86399)
    '23 hours, 59 minutes and 59 seconds'
    >>> distance_of_time_in_words(datetime(2008,3,21, 16,34),
    ... datetime(2008,2,6,9,45))
    '1 month, 15 days, 6 hours and 49 minutes'
    >>> distance_of_time_in_words(datetime(2008,3,21, 16,34), 
    ... datetime(2008,2,6,9,45), granularity='decade')
    'less than 1 decade'
    >>> distance_of_time_in_words(datetime(2008,3,21, 16,34), 
    ... datetime(2008,2,6,9,45), granularity='second')
    '1 month, 15 days, 6 hours and 49 minutes'
