No, you don't. You just need multiple clocks on the wall. This remains a widespread solution to determining whether or not your counterpart in Sydney is asleep

So instead of multiple clocks, you tape sticky notes on your one clock when different cities have high noon. You must always do the translation, with or without a universal time zone. The difference is that with universal time, it discards the entire set of translations around scheduling conversion that already happen, and it fixes the horrible mess of anyone living near a time zone boundary being in perpetual scheduling hell.

  Or I could just look at my wall. Pro tip for solution designers. Don't tell someone what they "must" do. It's the fast track to being ignored. Especially when a) you're badgering them to conform to some hairbrained sticky note engineering and b) they already have something that works.

    You could still have your wall of clocks. They would all show the same time but each clock face would be shaded half black and half white to show the average daylight period in that city.

    The "look at inopinatus' wall" solution does not scale well.

Or, if everyone used the same time zone, you just write down "Mary's work hours are 1:00-9:00," and then you know whether or not you can interrupt them.

I'd really like to see what a well made custom lit map would look like. What the clocks are approximating here is how long the sun has been shining on a given city. Something along the lines of this: http://www.solarsystemscope.com/daylightmap/ http://www.solarsystemscope.com/daylightmap/ Could give the viewer both the information they are roughly seeking and something significantly prettier than a bunch of clocks on a wall.

One of these (or a cheaper version) would work even better than a clock for every city you care about... https://www.geochron.com/ https://www.geochron.com/
