I have Kubernetes job which runs every day at 5 AM. Today I wanted to change it to 6 AM. My current time is 10 AM.

As soon as modified the time from 5 AM to 6 AM, I noticed that Kubernetes Cronjob immediately triggers the job even though my current time is 10 AM.

What is the reason for this? Is there any parameter which can be used to enable/disable this behavior?
