Task Scheduling and Cyclic

[spasobn]

What if I need to start task every 15s from 7:00 to 17:00
and start task every 30 minutes from 17:00 to 7:00. Do I
need two tasks for this solution.

If I use Cyclic Triggering event I can't do Start and End
time.
If I use Scheduler I can use Start and End time but can't
use step less then 1 minute.
What to do?

It's very interesting task.
See my example here, please. Download all of four tasks and import them into RoboTask.
Enable the task 4 after importing.

The main task will be launched each 15 s from 07:00 to 17:00 and each 30 min (or 1800 s) from 17:00 to 07:00

If you need more comments just drop a message to this topic.

Well, that's exactly what I need - to start some app every 5 minute during certain time interval (since 12.00 till 15.00). Thus according to spasobn's statement it should be possible. But I can not find, how to do it. It seems, that there is no such trigger "Start every..." there in a task properties. What do I miss?
Thanks!
