Assuming I understand you correctly, I can think of 2 ways of achieving a
dynamic delay:

1. Use the Pause action in the determinator to insert a pause before your
actions are executed.
- This is good for short delays, as it keeps the determinator thread alive,
but asleep, for the specified delay.
- This is also useful for accurate delays, as it can be specified in
milliseconds.
- Not so good for long delays (e.g. more than a few minutes) as you don't
want to leave the determinator thread running for too long
- You can't cancel a determinator once it's running if you wanted to.

2. Use the Suspend action.
- This is ideal for longer delays, as it kills the determinator thread, and
resumes it at the specified time.
What actually happens is that xPLHal creates a single (one-shot) event to
occur whenever the determinator should continue executing.
When this event fires, xPLHal continues executing the determinator where it
left off before it was suspended.

HTH,
