relativedelta fails if supplied with numpy.int64 as argument

[Will Furnass]

Would it be possible for relativedelta to be tweaked to allow it to accept numpy.int64 values as arguments?

At present this is what I get when using numpy 1.6 and dateutil 1.5:

datetime(2012,4,3) - dateutil.relativedelta.relativedelta(seconds = seconds[0])
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-80-043ad91e8ee3> in <module>()
      1 seconds = pl.array([3,4,5])
----> 2 datetime(2012,4,3) - dateutil.relativedelta.relativedelta(seconds = seconds[0])

/usr/local/lib/python2.7/dist-packages/dateutil/relativedelta.pyc in __rsub__(self, other)
    287
    288 def __rsub__(self, other):
--> 289 return self.__neg__().__radd__(other)
    290
    291 def __add__(self, other):

/usr/local/lib/python2.7/dist-packages/dateutil/relativedelta.pyc in __radd__(self, other)
    274 minutes=self.minutes,
    275 seconds=self.seconds,
--> 276 microseconds=self.microseconds))
    277 if self.weekday:
    278 weekday, nth = self.weekday.weekday, self.weekday.n or 1

TypeError: unsupported type for timedelta seconds component: numpy.int64
