Python에서 두 날짜 사이에 24시간이 지났는지 어떻게 정확하게 확인할 수 있나요?

def time_diff(last_updated):
    day_period = last_updated.replace(day=last_updated.day + 1,
                                      hour=1,
                                      minute=0,
                                      second=0,
                                      microsecond=0)
    delta_time = day_period - last_updated
    hours = delta_time.seconds // 3600
    # Check if 24 hours have passed
    if hours >= 24:
        print("hello")
    else:
        print("do nothing")

from datetime import datetime, timedelta

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

import time

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

from datetime import datetime, timedelta
from tzlocal import get_localzone # pip install tzlocal

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
