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


It appears to me that the simplest way to do this is

import datetimeepoch = datetime.datetime.utcfromtimestamp(0)def unix_time_millis(dt):    return (dt - epoch).total_seconds() * 1000.0


In Python 3.3, added new method timestamp:

import datetimeseconds_since_epoch = datetime.datetime.now().timestamp()

Your question stated that you needed milliseconds, which you can get like this:

milliseconds_since_epoch = datetime.datetime.now().timestamp() * 1000

If you use timestamp on a naive datetime object, then it assumed that it is in the local timezone. Use timezone-aware datetime objects if this is not what you intend to happen.


>>> 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()) * 10001312908681000.0
