Hue: scheduling?

I was wondering why scheduling is different here with Hue than in other switches. It has a single time schedule to turn on where as other switches have a range so it knows when to turn on and off. I haven’t been able to get this to work properly or turn off after a certain time. Is there some way to do this?

I’m referring to the setup through the following steps, I get to the Hue setup:

More > SmartThings Labs > Change the color and brightness of Philips hue bulbs when any of a variety of SmartThings is activated > At a Scheduled Time

It only shows the turn on time.
