How can I schedule a task in determinated hours?

Question

I want to run a task in week days, every 10 minutes between 8am and 17pm. I'm trying like this:

cron = BackgroundScheduler(daemon=True, timezone='UTC')
cron.add_job(service.test, trigger='cron',
             day_of_week='mon-fri', hour='7-16', minute=10)
cron.start()

but nothing happens. What am I doing wrong?

The documentation states that "After the scheduler has been started, you can no longer alter its settings.". I'm not sure if setting refers to new jobs as well. — Roy2012, Jul 06 '20 at 19:22
Also, UTC time right now is in the 20th hour, so it wouldn't work right now even if you added the job before you started the scheduler. — TheSinisterShadow, Jul 06 '20 at 19:23
@Roy2012 it was set before calling start, but i changed to see if it worked. — Ana Paula Lima, Jul 06 '20 at 19:25
So please change the code in the question to reflect that ... — Roy2012, Jul 06 '20 at 19:26
Look [here](https://www.timeanddate.com/time/zone/brazil) and try replacing UTC with your timezone. — TheSinisterShadow, Jul 06 '20 at 19:31
What do you mean by "nothing happens"? Does your program end? Do you somehow keep it running? — Roy2012, Jul 06 '20 at 19:40
Does the program continue to run as a process on your machine? — Roy2012, Jul 06 '20 at 19:42
yes. I'm starting to think that the problem it's the timezone, I tried to use my mine and raised a error " pytz.exceptions.UnknownTimeZoneError: 'BRT '" — Ana Paula Lima, Jul 06 '20 at 19:47
It uses pytz for timezones, so you can look at the list of valid timezones [here](https://stackoverflow.com/questions/13866926/is-there-a-list-of-pytz-timezones). I think `'Etc/GMT-3'` instead of `'BRT'` should work. — TheSinisterShadow, Jul 06 '20 at 19:51

So, after a lot of research I found out that the problem wasn't the timezone, but me that didn't understood the code.

this:

cron = BackgroundScheduler(daemon=True, timezone=get_localzone())
cron.add_job(service.test, 'cron', day_of_week=(
    'mon-fri'), hour='7-16', minute=10)

means that at the 10th minute of every hour of every week day my code would be called, and not that it's going to be called every 10 minutes. Here's the docs of Cron-style scheduling, if someone wants to read more about https://apscheduler.readthedocs.io/en/v2.1.2/cronschedule.html. Thanks everybody for helping!
