Ops, after reviewing this document, I've discovered a couple of typos.
A Tuesday 29 July 2008, Francesc Alted escrigué:
[snip]
> >>> series = numpy.array(['1970-01-01', '1970-02-01', '1970-09-01'],
> dtype='datetime64[D]')
> >>> series2 = series + numpy.timedelta(1, 'Y') # Add 2 years
^^^
the above line should read:
>>> series2 = series + numpy.timedelta(2, 'Y') # Add 2 years
> >>> series2
>
> array(['1972-01-01', '1972-02-01', '1972-09-01'],
> dtype='datetime64[D]') # the 'D'ay time unit has been chosen
[snip]
> >>> numpy.change_unit( numpy.array([1,2], 'T[Y]'), 'T[d]' )
>
> array([365, 731], dtype="datetime64[d]")
>
> or:
> >>> ref = numpy.datetime64('1971', 'T[Y]')
> >>> numpy.change_unit( numpy.array([1,2], 't[Y]'), 't[d]', ref )
>
> array([366, 365], dtype="timedelta64[d]")
^^^
the above line should read:
array([366, 731], dtype="timedelta64[d]")
