Why use this schedule
Frequent checks during working hours only, which cuts the number of runs by about two thirds compared with all day, every day.
- Order-desk polling
- Intraday risk or trade reports
- Helpdesk escalation checks

Things to watch out for in Kubernetes
- Kubernetes CronJobs run at most once per minute, and the controller checks about every ten seconds, so exact timing can drift by seconds.
- Day-of-week is 0-6 (or 7) with Sunday as 0, as in standard cron.
- Set spec.timeZone (Kubernetes 1.27+) to a name like Asia/Kolkata. Without it the schedule follows the controller's time zone, usually UTC.
The common mistake with this schedule
The last run is 17:45, not 17:00, because the hour range is 9-17 and the minute step still fires inside hour 17.
