How to determine the time when the Alert send message using ORA_CHK_TASK_REMINDER Alert Code runs

Summary:

I have implemented the ORA_CHK_TASK_REMINDER Alert Code to send reminder to employees who are yet to complete update on their information, but unable to schedule or determine the time the message will be sent to employee’s email. For Instance: We want the message to be sent to employee Every Tuesday by 7:30 am for employees who are yet to complete the task.

Again, at present the alert sent out message at 9:01 pm and I can't figure out how that time came about.

This job - Process a Predefined Resource Alert is associated with Alert. How can I change the timing of the job based on on the Journey Alert Code -
