Setting custom expiration date/time


When setting the custom expiration date/time for a task as:
_Task.CreatedOn + StrToTime('00:01')
This task isn't modified after almost two minutes. The following task is therefore also created after lamost two minutes.

Can you give some instructions on how WFS processes expired tasks? 
Is there some standard delay (timer) for expiring tasks?

The pending tasks are only processed when application calls WorkflowStudio1.WorkflowEngine.RunPendingWorkflowInstances method. 

It's up to the application to define when such method will run.
