Python Datetime Changes for UTC from 3.12

notes.md

Original blog: https://blog.miguelgrinberg.com/post/it-s-time-for-a-change-datetime-utcnow-is-now-deprecated

Example for new timezone aware objects:

from datetime import datetime, timezone

def aware_utcnow():
    return datetime.now(timezone.utc)

def aware_utcfromtimestamp(timestamp):
    return datetime.fromtimestamp(timestamp, timezone.utc)

def naive_utcnow():
    return aware_utcnow().replace(tzinfo=None)

def naive_utcfromtimestamp(timestamp):
    return aware_utcfromtimestamp(timestamp).replace(tzinfo=None)

print(aware_utcnow())
print(aware_utcfromtimestamp(0))
print(naive_utcnow())
print(naive_utcfromtimestamp(0))

Note

if you are using Python 3.11 or newer, you can replace datetime.timezone.utc with a shorter datetime.UTC.
