Idea

I think this is similar to another idea regarding playing a flash briefing (or any script) as an alarm. But this idea has a slightly different use case. I'd like to be able to input a timer for a skill. Examples: "Alexa, turn off my TV in 30 minutes" (as I sometimes like to watch TV as I drift off to bed) or "Alexa, turn on the lights for 20 minutes" (because my wife never forgets to turn them off!).
