When you create a new Timer, a built-in action is provided to allow you to programmatically wake the timer. This action is called Wake<Timer> and can be used in your application logic.
When the Wake<Timer> action is executed, the NextRun property of that Timer is updated to the present time. The timer will then be handled by the Platform Server and executed according to its priorities. See how priorities are handled.
The Wake<Timer> action does not receive any input parameters and does not return any output parameters.
