What is the recommended method to convert a datetime object to millisecond unix timestamp?

Question

If I have a datetime object like

datetime.datetime(2016,4,5,10,4,7,000)

How would I convert it to unix timestamp with millisecond accuracy?

I am using python version 2.7.10. The solution here (How can I convert a datetime object to milliseconds since epoch (unix time) in Python?) using total_seconds seems to round to the nearest second on my system.

It doesn't "round", it uses a function whose resolution is whole seconds. You can extract the `microseconds` field from the `timedelta` object and add it as an additional step. — tripleee, Jul 01 '16 at 06:16

Use the timestamp() method.

>>> import datetime
>>> datetime.datetime(2016,4,5,10,4,7,000).timestamp()
1459875847.0
>>> datetime.datetime(2016,4,5,10,4,7,123456).timestamp()
1459875847.123456

this is not available in python < 3.3. – sakurashinken Jun 30 '16 at 23:14
And is that what you're using? You never specified. – TigerhawkT3 Jun 30 '16 at 23:15
I edited the question to reflect that. – sakurashinken Jun 30 '16 at 23:23

If you dont mind an inefficient solution then you can change system date and time, check this for reference and then get the time stamp using time.time().

Better methods must exist, its just a work around.
