Why Is There a Large Difference Between Job Execution Time and Start Time of a Job?

On the Running History page, there is a large difference between Job Execution Time and Start Time, as shown in the figure below. Job Execution Time is the time when the job is expected to be executed. Start Time is the time when the job starts to be executed.

In Data Development, a maximum of five instances can be concurrently executed in a job. If Start Time of a job is later than Job Execution Time, the job instances in the subsequent batch will be queued.

If you find that the difference between Job Execution Time and Start Time becomes large, adjust Job Execution Time accordingly.
