Oh yes, I think most towers have always had that. However, using TR's scenario for example , when the B773 rotates you hit the start button on a stop-watch, all you have to do then is wait for the required interval & away goes the next. No need for mental arithmetic, fiddling the minute - is 30 seconds the minute before or after, that sort of thing. Just one less thing to occupy your attention & let you keep your eyes on the outside world, not your desk :-)
