Confirmed in current development. Note that things have changed and the
initial array creation will fail (no unit). The searchsorted will work if
searching for a datetime:
In [10]: x = np.array([1,2,3], 'datetime64[D]')
In [11]: x.searchsorted(datetime64(2,'D'))
Out[11]: 1
So the failure is one of raising an appropriate error message.
Please open a ticket.
