The constructor handles keywords, so you'll only have to give those parameters which should be changed when you add the relative to an absolute DateTime instance. Adding RelativeDateTime instances is supported with the following rules: deltas will be added together, right side absolute values override left side ones. Adding RelativeDateTime instances to DateTime instances will return DateTime instances with the appropriate calculations applied, e.g. to get a DateTime instance for the first of next month, you'd call now() + RelativeDateTime(months=+1,day=1). i c C s | | _ | | _ | | d | _ | | _ | | _ | | _ | | _ | | _ | | _ | | _ | | _ | | _ | o t | d j | | _ n d S( Ni i ( t yearst selft monthsRS t weeksR" R# R$ R2 R3 R R% R& R' t weekdayRB ( Rr Rq Rs RS R2 R3 R R" R# R$ R% R& R' Ru Rt ( ( R t __init__ s c C s: | | t o t } | i | i | _ | i | i | _ | i | i | _ | i p | i | _ | i p | i | _ | i p | i | _ | i p | i | _ | i | i | _ | i | i | _ | i | i | _ | i p | i | _ | i p | i | _ | i p | i | _ | Sn t d d S( Ns can't add the two types( t isinstancet otherRp t rRr Rq Rs RS R" R# R$ Ru R2 R3 R R% R& R' RK ( Rr Rx Rw Ry ( ( R t __add__ s" c C s | | | o| i d j o | i | i } n | i | i } | i d j o | i | i } n | i | i } | i d j o | i } n | i } | d j o | d } | d } n | | i } | i d j o | i | i } n | i | i } | i d j o | i | i } n | i | i } | i d j o | i | i } n | i | i } | d j p | d j o* | d } | | d } | d d } n | i d j o+ | | | d | | d | | | Sn | i \ } } | | | d | | d | | | } | d j o | | | i Sq | d j oW | | i d } | | i } | d j o | | | d d Sq| | | d Sq | | i | i } | | i } | d j o | | | d d Sq | | | d Sn t d d S( Ni i i i s can't add the two types( Rw Rx RI Rr R" R Rq R# Rs R$ RS R% R2 R& R3 R' R Ru R R1 t day_of_weekt indext dt firstt difft days_in_montht lastRK ( Rr Rx Rw RI R R1 R| R R} R% R# R{ R' R" R R$ R& R~ ( ( R t __radd__ sZ +) c C s: t | t o t } | i | i | _ | i | i | _ | i | i | _ | i p | i | _ | i p | i | _ | i p | i | _ | i p | i | _ | i | i | _ | i | i | _ | i | i | _ | i p | i | _ | i p | i | _ | i p | i | _ | Sn t d d S( Ns can't subtract the two types( Rw Rx Rp Ry Rr Rq Rs RS R" R# R$ Ru R2 R3 R R% R& R' RK ( Rr Rx Ry ( ( R t __sub__d s" c C s/ | | t o | | i Sn t d d S( Ns can't subtract the two types( Rw Rx RI Rr t __neg__RK ( Rr Rx Rw R ( ( R t __rsub__ s c C s t } | i | _ | i | _ | i | _ | i | _ | i | _ | i | _ | i | _ | i | _ | i | _ | i | _ | i | _ | i | _ | i | _ | S( N( Rp Ry Rr Rq Rs RS R" R# R$ Ru R2 R3 R R% R& R' ( Rr Ry ( ( R R s c C s | i d j o | i d j o | i d j o | i d j o | i d j o | i d j ox | i d j oh | i d j oX | i d j oH | i d j o8 | i d j o( | i d j o | i d j o d Sn d Sd S( Ni i ( Rr R" R Rq R# Rs R$ Ru RS R% R2 R& R3 R' R ( Rr ( ( R t __nonzero__ s c C sy t | } t } | | i | _ | | i | _ | | i | _ | | i | _ | | i | _ | | i | _ | S( N( R Rx t factorRp Ry Rr Rq Rs RS R2 R3 R ( Rr Rx R Ry ( ( R t __mul__ s c C s | i d t | S( Ni ( Rr R R Rx ( Rr Rx ( ( R t __div__ s c C s2 g } | i } | i d j o | d | i n* | i o | d | i n | d | i d j o | d | i n* | i o | d | i n | d | i d j o | d | i n* | i o | d | i n | d | i o. | d t | i d d | i d f n | d | i d j o | d | i n* | i o | d | i n | d | i d j o | d | i n* | i o | d | i n | d | i d j o | d | i n* | i o | d | i n | d | | d S( Ns %04i-s (%0+5i)-s YYYY-s %02i-s (%0+3i)-s MM-s %02is (%0+3i)t DDs %s:%ii i i R@ s %02i:s (%0+3i):s HH:s MM:t SSt ( t lt appendRr R" R Rq R# Rs R$ RS Ru t WeekdayR% R2 R& R3 R' R t join( Rr R R R ( ( R t __str__ sH . c C s# d | i i | i t | f S( Ns <%s instance for '%s' at 0x%x>( Rr t __class__R R t id( Rr ( ( R t __repr__ s (# R R t __doc__Rq Rs RS R R" R# R$ R2 R3 R R% R& R' Ru Rv Rw Rz RI R R1 R R R R R R t __rmul__R R R R R ( ( ( R Rp s4 3 J /c O s t | d j oh | d } d k } t | | i j o d k } | i | Sq t | t o | Sq t d n t t | | Sd S( s RelativeDateTimeFrom(*args,**kws) Generic RelativeDateTime instance constructor.
