apscheduler in Flask executes twice

Question

I have problem when i am using apscheduler in my flask application.

In my view.py file i am writing like this

import time
from apscheduler.scheduler import Scheduler

def test_scheduler():
     print "TEST"
     print time.time()


sched = Scheduler()
sched.add_interval_job(test_scheduler, seconds=5)
sched.start()

And then this method test_scheduler() executes twice in every five second

TEST 1360844314.01 TEST 1360844314.2

Answer 1

I've made it, I added in add_interval_job parameter to start after a certain time point

sched.add_interval_job(test_scheduler, seconds=5, start_date='2013-02-13 00:00')
