Convert time to unix time

Converting unix timestamp string to readable date in Python

When I do time.time() I get something like: 1342648659.223746. How can I convert it to unix time that looks like this: 2012-07-18T21:42:00Z?

Answer 1

Python's standard datetime module is quite handy for all kinds of date/time manipulation.

For your particular problem, the isoformat() method is handy. For example, if you already have a time in seconds since the Epoch (such as your 1342648659.223746):

>> from datetime import datetime
>> datetime.fromtimestamp(1342648659.223746).isoformat()
== '2012-07-18T23:57:39.223746'

And if you just want the current (UTC) time, ISO formatted:

>> datetime.utcnow().isoformat()
== '2012-07-19T00:06:45.724468'

If you absolutely require the timezone information in your output (i.e. the Z for UTC in your example), you'll either have to append it manually, or fall back to using strftime:

>> datetime.utcnow().strftime('%Y-%m-%dT%H:%M:%SZ')
== '2012-07-18T22:11:05Z'

Answer 2

You should use the datetime module as below:

>>> import datetime
>>> d = datetime.datetime.fromtimestamp(27654727.23)
>>> print d
1970-11-16 22:52:07.230000

You could pass the timestamp to the fromtimestamp() function.
