What this teaches
Name the cities and the question you want answered, and the page works out the time differences for you.
- "New York, London, Berlin, Tokyo and Sydney" names the cities; their time zones and daylight saving come from the browser.
- "a slider to find a meeting hour" turns the question into one control.
- The change adds a colour for working hours and a way to add cities.

Known limitations
- The green "within working hours" marks follow the slider's hour, not the current time shown above them.
- With these five cities no single hour is inside everyone's working day; the summary says how many fit.
- Working hours are 9:00 to 17:00 for every city.
- The meeting time takes the current minute, so 12 can read 12:37 and moves on with the clock.
