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

This is how I do it:

from datetime import datetime
from time import mktime

dt = datetime.now()
sec_since_epoch = mktime(dt.timetuple()) + dt.microsecond/1000000.0

millis_since_epoch = sec_since_epoch * 1000
