I want to subtract the two date time object using python those are in utc format("%Y-%m-%d %H:%M:%S.%f").How can i subtract the two object, the output should be in ITC format(("%Y-%m-%d %H:%M:%S.%f").Can anyone please help me.

logout time:2019-04-23 04:34:18.002699

now_utc = datetime.now() >>> now_utc datetime.datetime(2019, 4, 23, 11, 15, 42, 554213) >>> from pytz import timezone >>> from tzlocal import get_localzone >>> now_utc = datetime.now(timezone('UTC')) >>> now_utc datetime.datetime(2019, 4, 23, 5, 46, 18, 313518, tzinfo=) — navya sri, Apr 23 '19 at 05:47

If they're both `datetime` objects you can just do `a - b`, where `a` and `b` are the two different datetimes. — Recessive, Apr 23 '19 at 05:59

Use dateutil.parser:

import dateutil.parser as dparser

in_time = 'login in-time: 2019-04-23 04:22:50.421406'
out_time = 'logout time:2019-04-23 04:34:18.002699'

str((dparser.parse(out_time, fuzzy=True) - dparser.parse(in_time, fuzzy=True)))

Output:

'0:11:27.581293'

Subtract the two date time objects:

from datetime import datetime


t1 = datetime(2019,4,23,8,22,50,421406)
t2 = datetime(2019,4,23,4,55,18,155555)
t3 = t1 -t2
print(t3)
