BUG!! Apscheduler modify do not work when you update a cron job from later to early

I found a bug that, if you firstly add a cron style job which will be scheduled at tomorrow, such as notify_job (trigger: cron[day_of_week='0-6', hour='0-2', minute='0-59', second='0-59'], next run at: 2017-10-25 00:00:00 CST)

then if you modify it by early, such as notify_job (trigger: cron[day_of_week='0-6', hour='*/', minute='*/5', second='*/20'], next run at: 2017-10-25 00:00:00 CST)

it will think hour is tomorrow; it does not work!!! following is my code snippet, it is dangerous！

task1 = scheduler.add_job(job_func, trigger='cron', day_of_week='0-6', hour='19,21', minute='*/5', second='0,10,20,30,30,40,40,50', args=[action, 'disk1', 'disk1'], end_date='2017-12-30')
job_func = clouds.cron.jobs.notify_job
task2 = scheduler.add_job(job_func, trigger='cron', day_of_week='0-6', hour='0-2', minute='0-59', second='0-59', args=['disk2', succ_callback, fail_callback])
task3 = scheduler.add_job(job_func, trigger='interval', seconds=20, args=['disk3', succ_callback, fail_callback])

scheduler.print_jobs()

time.sleep(5)
scheduler.remove_job(task3.id)

scheduler.print_jobs()


time.sleep(5)

from apscheduler.triggers.cron import CronTrigger
trigger = CronTrigger(day_of_week='0-6', hour='*', minute='*/5', second='*/20', end_date='2017-10-31')
# import pdb
# pdb.set_trace()
scheduler.modify_job(task2.id, trigger=trigger, args=[action, succ_callback, fail_callback], coalesce=True)
# scheduler.reschedule_job(task2.id)

print scheduler.get_job(task2.id)

time.sleep(10)
print 'pausing......'
scheduler.pause()

time.sleep(5)
print 'resuming......'
scheduler.resume()

output：

I also query mysql database to make sure it is, and the time in next_run_time always keep the same in tomorrow!

@agronholm I FOUND reschedule_job function can not modify job’s function args parameter, right?

sched.reschedule_job(self.id,
                     name=self.name,
                     misfire_grace_time=options.misfire_grace_time,
                     max_instances=options.max_instances,
                     coalesce=options.coalesce,
                     trigger=trigger,
                     func=cronjob,
                     args=[data['action'],None,None])

just trigger is valid, other do not! so if i want to modify and take effective immediately， I must first use modify and then use reschedule

I think reschedule and modify job is very buggy!
