date - Convert numpy.datetime64 to string object in python

Question

I am having trouble converting a python datetime64 object into a string. For example:

t = numpy.datetime64('2012-06-30T20:00:00.000000000-0400')

Into:

'2012.07.01' as a  string. (note time difference)

I have already tried to convert the datetime64 object to a datetime long then to a string, but I seem to get this error:

dt = t.astype(datetime.datetime) #1341100800000000000L
time.ctime(dt)
ValueError: unconvertible time

Answer 1

Solution was:

import pandas as pd 
ts = pd.to_datetime(str(date)) 
d = ts.strftime('%Y.%m.%d')
