Question

How do I convert a numpy.datetime64 object to a datetime.datetime (or Timestamp)?

In the following code, I create a datetime,

I've come back to this answer more times than I can count, so I decided to throw together a quick little class, which converts a Numpy datetime64 value to Python datetime value. I hope it helps others out there.

from datetime import datetime
import pandas as pd

class NumpyConverter(object):
    @classmethod
    def to_datetime(cls, dt64, tzinfo=None):
        """
        Converts a Numpy datetime64 to a Python datetime.
        :param dt64: A Numpy datetime64 variable
        :type dt64: numpy.datetime64
        :param tzinfo: The timezone the date / time value is in
        :type tzinfo: pytz.timezone
        :return: A Python datetime variable
        :rtype: datetime
        """
        ts = pd.to_datetime(dt64)
        if tzinfo is not None:
            return datetime(ts.year, ts.month, ts.day, ts.hour, ts.minute, ts.second, tzinfo=tzinfo)
        return datetime(ts.year, ts.month, ts.day, ts.hour, ts.minute, ts.second)

I'm gonna keep this in my tool bag, something tells me I'll need it again.
