How to add hours to current time in python

from datetime import datetime, timedeltanine_hours_from_now = datetime.now() + timedelta(hours=9)#datetime.datetime(2012, 12, 3, 23, 24, 31, 774118)

And then use string formatting to get the relevant pieces:

>>> '{:%H:%M:%S}'.format(nine_hours_from_now)'23:24:31'

If you're only formatting the datetime then you can use:

>>> format(nine_hours_from_now, '%H:%M:%S')'23:24:31'

Or, as @eumiro has pointed out in comments - strftime

Import datetime and timedelta:

>>> from datetime import datetime, timedelta>>> str(datetime.now() + timedelta(hours=9))[11:19]'01:41:44'

But the better way is:

>>> (datetime.now() + timedelta(hours=9)).strftime('%H:%M:%S')'01:42:05'

You can refer strptime and strftime behavior to better understand how python processes dates and time field

This works for me working with seconds not hours and also using a function to convert back to UTC time.

from datetime import timezone, datetime, timedelta import datetimedef utc_converter(dt):    dt = datetime.datetime.now(timezone.utc)    utc_time = dt.replace(tzinfo=timezone.utc)    utc_timestamp = utc_time.timestamp()    return utc_timestamp# create start and end timestamps_now = datetime.datetime.now()str_start = str(utc_converter(_now))_end = _now + timedelta(seconds=10)str_end = str(utc_converter(_end))
