How can I convert a datetime object to milliseconds since epoch (unix time) in Python?

Question

I have a Python datetime object that I want to convert to unix time, or seconds/milliseconds since the 1970 epoch.

How do I do this?

Answer 1

>>> import datetime
>>> # replace datetime.datetime.now() with your datetime object
>>> int(datetime.datetime.now().strftime("%s")) * 1000 
1312908481000

Or the help of the time module (and without date formatting):

>>> import datetime, time
>>> # replace datetime.datetime.now() with your datetime object
>>> time.mktime(datetime.datetime.now().timetuple()) * 1000
1312908681000.0
