When using a User Interaction element in your workflow you might want to have it timeout after a certain amount of time. A user interaction accepts an input parameter of the Date-type that contains the date and time when the user interaction should timeout if it is not answered.
In the image below you see a workflow that contains a Scriptable task used to create the date_time variable to be used in the user interaction.
The Javascript code from the Scriptable task is this (without the comments and logging):
timeout_date = new Date();
timeout_date.setTime( timeout_date.getTime() + (86400000) );
timeout_date.setTime( timeout_date.getTime() + (86400000) );
What is done here is that we get the current date and time and add the amount of milliseconds that represents one day. The math for this is:
1000 (milliseconds) * 3600 (seconds in an hour) * 24 (hours in a day) = 86,400,000
This will make the user interaction timeout after one day. If you would it to timeout after two hours the math would be: 1000 (milliseconds) * 3600 (seconds in an hour) * 2 = 7,200,000
The user interaction element then uses your date_time variable as input to decide when to timeout. When it does it throws an error that would end your workflow with a failed condition. If that is what you want then that's fine. But if you want to take action when it has timeout add a next element to the error channel of the input presentation to handle that. You can see that representation in the below image.
