python datetime

from datetime import datetime as dt
# from string
datetime = dt.strptime('2022-01-01 23:59:59', '%Y-%m-%d %H:%M:%S')

# to string

python date time

>>> import pytz
>>> from datetime import datetime, date, time
# To get the UTC time of current day (today) for a given time zone
# use the localize() function of the pytz. 
# The reason for this is that the localize() takes into account the Day Time Saving
# which niether the datetime constructors nor replace() account for.
# 
# To for example, the utc time of today in australia time zone:

import pytz
from datetime import datetime, date, time

# set time zone
tz = pytz.timezone("Australia/Melbourne")

# Get today's date in the current time zone (i.e local time)
todaydate = date.today() # you can also use date(2022, 2, 8)

# Get midnight of today (still local time)
# note time() without arguments will result to midnight

midnight_local = datetime.combine(todaydate, time())

print midnight_local

# convert this midnight datetime to the midnight datetime
# in the given time zone. In this case autralia time zone
austra_midnight = tz.localize(midnight_local)

print austra_midnight

# convert the midnight time in australia time zone to UTC
midnight_austra_utc = austra_midnight.astimezone(pytz.uct)

print midnight_austra_utc
