What happened?

This issue was reported in #807 for SQLAlchemyDataStore and also mentioend here, but seems not fixed yet for in-memory data store. When a paused schedule created with timezone reaches its trigger time, the next fire time is not correctly updated, resulting in infinite rapid retrying of the scheduler.

How can we reproduce the bug?

The following code demonstrates the problem:

import sys
from zoneinfo import ZoneInfo
from apscheduler import Scheduler
from apscheduler.triggers.cron import CronTrigger
import logging

def hello_world():
    logging.root.info("hello")

logging.getLogger().addHandler(logging.StreamHandler(sys.stdout))
logging.root.setLevel(logging.DEBUG)
scheduler = Scheduler(logger=logging.root)
cron_trigger = CronTrigger(second = "*", timezone = ZoneInfo("America/New_York"))
schedule_id = scheduler.add_schedule(hello_world, cron_trigger)
scheduler.start_in_background()
scheduler.pause_schedule(schedule_id)

Then, upon running this code, the following output can be observed:

Using selector: KqueueSelector
Added new schedule (task='__main__:hello_world', trigger=CronTrigger(year='*', month='*', day='*', week='*', day_of_week='*', hour='*', minute='*', second='*', start_time='2024-10-15T16:25:22.965474-04:00', timezone='America/New_York')); next run time at 2024-10-15 16:25:23-04:00

Agreed, on master this does not seem to happen.
