[web-alarms] Remove timezone support from Task Scheduler API

Hi,

It was proposed during the last SysApps face to face in Toronto to remove timezone support from the Task Scheduler API [1].
This would essentially mean removing the TimezoneDirective [2] from the API and pass a number of second since epoch to schedule a task instead of an EcmaScript Date (e.g. by using "Date.now() + n").

The change was proposed for several reasons:
- The TimezoneDirective is not very clear, may be confusing to the developers and makes the API more complex,
- The current timezone support is not sufficient to handle calendar use cases anyway since you cannot explicitly specify which timezone to use,
- The Date object may be removed from Web IDL [3] as its use was discouraged on es-discuss [4].

I am sending this message to the mailing list to gather broader feedback before updating the specification draft. Please let us know how you feel about this change.
