Q Light Controller+

Hi, I'd like to change the time on the clock widget. As I wanna control by the webserver the time to start and to finish a Show. I was thinking if there's a way to use variables to have a time-to-start and a time-to-finish var that I could change.

Or there's another way I didn't think about?

Thanks

Start and kill a process is the only way I can think of...
