40 ``datetime64`` -- an absolute time.
50 The ``datetime64`` represents an absolute time.  Internally it is
134 combined with either the string for a datetime64 ('M8') or a
143 ``datetime64``
163 Building a ``datetime64`` dtype
170   dtype('datetime64[us]')
193   repr(t[1]) -->  datetime64(1199164177, 's')
198                       dtype='datetime64[s]')
210   numpy.array(['1979', '1980'], 'M8[Y]') == numpy.datetime64('1980', 'Y')
313 Here is an example of use for the ``datetime64``::
315   In [5]: numpy.datetime64(42, 'us')
316   Out[5]: datetime64(42, 'us')
318   In [6]: print numpy.datetime64(42, 'us')
321   In [7]: print numpy.datetime64(367.7, 'D')  # decimal part is lost
325   Out[8]: datetime64(20273063, 'm')
330   In [10]: t = numpy.zeros(5, dtype="datetime64[ms]")
340   Out[13]: array([267859210457, 0, 0, 0, 0], dtype="datetime64[ms]")
346   dtype('datetime64[ms]')
359   In [8]: t1 = numpy.zeros(5, dtype="datetime64[ms]")
361   In [9]: t2 = numpy.ones(5, dtype="datetime64[ms]")
383 ``datetime64`` vs ``datetime64``
418 ``datetime64`` vs ``timedelta64``
425   Out[10]: array([1971, 1971, 1971, 1971, 1971], dtype=datetime64[Y])
428   Out[11]: array([1969, 1969, 1969, 1969, 1969], dtype=datetime64[Y])
443   dtype='datetime64[D]')
447   dtype='datetime64[D]')  # the 'D'ay time unit has been chosen
493 date (NumPy datetime64 scalar) that will be used to allow the conversion
517   In[10]: t1 = numpy.zeros(5, dtype="datetime64[s]")
523   In[12]: print t1.astype('datetime64[D]')
539   In[13]: numpy.zeros(5, dtype="datetime64[s]").astype('timedelta64')
548   In[10]: t1 = numpy.arange(5, dtype="datetime64[D]")
553   In[12]: t2 = t1.astype("datetime64[B]")
561   In[14]: t3 = t2.astype("datetime64[D]")
