Returns a RelativeDateTime instance for the specified relative
time. 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 S( s5 RelativeDateTimeDiff(date1,date2)
Returns a RelativeDateTime instance representing the difference
between date1 and date2 in relative terms.
The following should hold:
date2 + RelativeDateDiff(date1,date2) == date1
for all dates date1 and date2.
Note that due to the algorithm used by this function, not the
whole range of DateTime instances is supported; there could
also be a loss of precision.
XXX There are still some problems left (thanks to Carel
Fellinger for pointing these out):
29 1 1901 -> 1 3 1901 = 1 month
29 1 1901 -> 1 3 1900 = -10 month and -28 days, but
29 1 1901 -> 28 2 1900 = -11 month and -1 day
and even worse:
>>> print RelativeDateDiff(Date(1900,3,1),Date(1901,2,1))
YYYY-(-11)-DD HH:MM:SS
with:
>>> print Date(1901,1,29) + RelativeDateTime(months=-11)
1900-03-01 00:00:00.00
>>> print Date(1901,2,1) + RelativeDateTime(months=-11)
