두 Python `datetime` 객체 사이에 24시간이 지났는지 효율적으로 확인하려면 어떻게 해야 합니까?

from datetime import datetime, timedelta

if (datetime.utcnow() - last_updated) > timedelta(hours=24):
    # More than 24 hours passed since last_updated

import time

DAY = 86400
now = time.time()
then = time.mktime(last_updated.timetuple())
if (now - then) > DAY:
    # More than 24 hours passed since last_updated

from datetime import datetime, timedelta
from tzlocal import get_localzone

tz = get_localzone()
then = tz.normalize(tz.localize(last_updated))
now = datetime.now(tz)
if (now - then) > timedelta(hours=24):
    # More than 24 hours passed since last_updated
