Thanks for highlighting that, I see it more clearly
By the way I still don't see it in the process, I only see:
- the "get the timed task handle" step
- and the "get the timeout" step

I agree this is a problem for the listed use cases
This is another good reason:
- to use a different method name for this purpose
- to provide a better solution to these needs
I'm not sure which one could be either correct and intuitive
- scheduleTask() ?
- setTaskDate() ?
- setCron() ?
anything else ?
The question would be, if the computer goes to sleep, should the user agent :
1 - wake up the computer to execute the function ?
2 - wait until it wake up to execute it ?
3 - ignore the handler if its to late ?
The choice between options 2 and 3, could be settable as part of the method signature.
The first option looks more sensible and in my opinion should require to activate a setting or ask the user to accept for the current domain
This show up another requirement
As for a Web "Application", User Agents may provide a setting dialog so it could ask to the user to accept a list of option for the application
This way, the user won't miss line on top of the page asking authorizations for each ones
setDomainSettings( message, required, optional);
where "required" and "optional" parameters would expect a list of options to activate including:
- storage with specific size
- allow popup
- remember password
