Wolfram Language code: cities = {"Lima", "Santa Fe", "Andover", "Giza", "Phnom Penh", "Sian"};
Wolfram Language code: wtime = DateString[TimeZone -> CityData[#, "TimeZone"]]& /@ cities;
Wolfram Language code: gauges = MapThread[ClockGauge[#, PlotLabel -> Style[#2, Large, Bold]]&, {wtime, cities}];
Wolfram Language code: Grid[Partition[gauges, 3], Spacings -> {0, 0}]
