from pytz import timezone 
from datetime import datetime

ind_time = datetime.now(timezone("Asia/Kolkata")).strftime('%Y-%m-%d %H:%M:%S.%f')
print(ind_time)
>>> "2020-08-28 11:56:37.010822"

可以在datetime模块中使用timedelta对象：
由于印度标准时间（IST）比协调世界时（UTC）早5.5小时，因此我们可以将UTC时间移动到5小时30分。

import datetime as dt

dt_India_naive = dt.datetime.utcnow() + dt.timedelta(hours=5, minutes=30)
dt_India_aware = dt.datetime.now(dt.timezone(dt.timedelta(hours=5, minutes=30)))

dt_UTC_naive = dt.datetime.utcnow()
dt_UTC_aware = dt.datetime.now(dt.timezone.utc)

max_len = len(max(['UTC Time', 'Indian Time'], key=len))

print(f"{'UTC Time'   :<{max_len}} - {dt_UTC_aware:%d-%b-%y %H:%M:%S}")
print(f"{'Indian Time':<{max_len}} - {dt_India_aware:%d-%b-%y %H:%M:%S}")

# Both offset-naive and offset-aware will provide same results in this sitatuiion

结果：

UTC Time    - 20-Feb-23 03:29:12
Indian Time - 20-Feb-23 08:59:12

你可以用pytz来做：

import datetime,pytz

dtobj1=datetime.datetime.utcnow()   #utcnow class method
print(dtobj1)

dtobj3=dtobj1.replace(tzinfo=pytz.UTC) #replace method

#print(pytz.all_timezones) => To see all timezones
dtobj_india=dtobj3.astimezone(pytz.timezone("Asia/Calcutta")) #astimezone method
print(dtobj_india)

结果：

2020-08-28 06:01:13.833290
2020-08-28 11:31:13.833290+05:30
