Does Python’s time.time() return the local or UTC timestamp?

by

The time.time() function returns the number of seconds since the epoch, as a float. Note that “the epoch” is defined as the start of January 1st, 1970 in UTC. So the epoch is defined in terms of UTC and establishes a global moment in time. No matter where on Earth you are, “seconds past epoch” (time.time()) returns the same value at the same moment.

Here is some sample output I ran on my computer, converting it to a string as well.

>>> import time
>>> ts = time.time()
>>> ts
1355563265.81
>>> import datetime
>>> datetime.datetime.fromtimestamp(ts).strftime('%Y-%m-%d %H:%M:%S')
'2012-12-15 01:21:05'
>>>

The ts variable is the time returned in seconds. I then converted it to a human-readable string using the datetime library.
