功能实现：每秒输出当前时间

from apscheduler.scheduler import Scheduler
import datetime

schedudler = Scheduler(daemonic=False)


@schedudler.cron_schedule(day='*/1', hour='*/1',minute='*/1',second='*/1')
def quote_send_sh_job():
    print('a simple cron job start at', datetime.datetime.now())


schedudler.start()

APScheduler版本为2.1.2
