You don't need to add extra parameters to the Intent. On TimedNotificationPublisher you can get the original notification including the schedule.

But I don't think that's even needed, I think calling notification.when = System.currentTimeMillis(); in TimedNotificationPublisher should cover all cases, for on, every and at, so we can even remove the current code for handling the at and that single line should show the correct time for all of them.
