Hi all,
1. why do some say that the time module is more accurate than the timeit
module?
s = time.time()
or
s = timeit.timeit()
2. Why is it that both modules never return the same answer on each run?
Thank you for your response.

Hi,
I've been trying to code a timer that tells you how long you've been on the

An example, utc time -02:30 and dst +1 :

isUTCNegative = True
dst = datetime.time(1,0)
Now I would the difference of both times.
