.Run On Start
The tab labeled Options will let you set the CD timer to be started automatically the next time you run CD. In other words, if you run a scheduled job and then end that job and close CD, the next time you open CD, that job will be reopened and set to run automatically as though you had entered the data and clicked the Begin button. This means that if you’ve scheduled a job that runs every second week, for example, when the timer automatically restarts the CD scheduler will recalculate the next run based on today’s date regardless of the length of time that might have been remaining before the next run when you last closed CD. You can turn this option off by clearing the check box labeled Automatically restart the timer on program load
.
Time Overrun Handling
In the event that a Time Based job runs longer than the time interval you allowed for the job to run, CD gives you two options for handling the circumstance.
If you select Immediately after the current job finishes, the next job will begin running immediately upon completion of the preceding run. This means that the jobs will be running continuously, back-to-back regardless of the time interval entered. Selecting Skip this run and set the timer for the next one, causes one run of the program to be skipped but runs at the next scheduled time. Please see Table 3 for an example of this where the interval is set for every 15 minutes, but the running time of the job is 20 minutes. Effectively what happens in this case is the job will run every other time.

Table 3. Based on a 15 minute interval, a Next Target Time is calculated. In this example the job takes 20 minutes to run, so the Next Target Time has been missed. With the ‘Skip’ option selected, CD will realize the next target time has past and will recalculate a new target time based on the interval specified by the user. The job will run at 1:00, 1:30, 2:00 etc., half as often as expected.
