Python Create unix timestamp five minutes in the future

Question

I have to create an "Expires" value 5 minutes in the future, but I have to supply it in UNIX Timestamp format. I have this so far, but it seems like a hack.

def expires():     '''return a UNIX style timestamp representing 5 minutes from now'''     epoch = datetime.datetime(1970, 1, 1)     seconds_in_a_day = 60 * 60 * 24     five_minutes = datetime.timedelta(seconds=5*60)     five_minutes_from_now = datetime.datetime.now() + five_minutes     since_epoch = five_minutes_from_now - epoch     return since_epoch.days * seconds_in_a_day + since_epoch.seconds 

Is there a module or function that does the timestamp conversion for me?

Answer 1

Another way is to use calendar.timegm:

future = datetime.datetime.utcnow() + datetime.timedelta(minutes=5) return calendar.timegm(future.timetuple()) 

It's also more portable than %s flag to strftime (which doesn't work on Windows).

Answer 2

Now in Python >= 3.3 you can just call the timestamp() method to get the timestamp as a float.

import datetime current_time = datetime.datetime.now(datetime.timezone.utc) unix_timestamp = current_time.timestamp() # works if Python >= 3.3  unix_timestamp_plus_5_min = unix_timestamp + (5 * 60)  # 5 min * 60 seconds
