How Can I Convert From Utc Time To Local Time In Python?

So, I want to convert UTC date time 2021-08-05 10:03:24.585Z to Indian date time how to convert it? What I tried is from datetime import datetime from pytz import timezone st = '

Solution 1:

parse the date/time string to UTC datetime correctly and use astimezone instead of replace to convert to a certain time zone (option for newer Python version (3.9+) in comments):

from datetime import datetime
# from zoneinfo import ZoneInfofrom dateutil.tz import gettz

st = "2021-08-05 10:03:24.585Z"
zone = "Asia/Kolkata"# dtUTC = datetime.fromisoformat(st.replace('Z', '+00:00'))
dtUTC = datetime.strptime(st, '%Y-%m-%d %H:%M:%S.%f%z')

# dtZone = dtUTC.astimezone(ZoneInfo(zone))
dtZone = dtUTC.astimezone(gettz(zone))

print(dtZone.isoformat(timespec='seconds'))
# 2021-08-05T15:33:24+05:30

If you just need local time, i.e. your machine's setting, you can use astimezone(None) as well.

Solution 2:

You can use sth like this:

from datetime import datetime
from dateutil import tz

from_zone = tz.gettz('UTC')
to_zone = tz.gettz('Asia/Kolkata')

utc = datetime.strptime('2011-01-21 02:37:21', '%Y-%m-%d %H:%M:%S')

utc = utc.replace(tzinfo=from_zone)

central = utc.astimezone(to_zone)
