HI everyone, is it possible to change the UTC to SGT on the clock view model and the timeline??
var clock = new Cesium.Clock({

startTime : Cesium.JulianDate.fromIso8601(“2017-08-04T01:19:20-08:00”),

currentTime : Cesium.JulianDate.fromIso8601(“2017-08-05T01:19:20-08:00”),

stopTime : Cesium.JulianDate.fromIso8601(“2017-08-09T01:19:21-08:00”),

clockRange : Cesium.ClockRange.LOOP_STOP,

clockStep : Cesium.ClockStep.SYSTEM_CLOCK_MULTIPLIER

});

var viewer = new Cesium.Viewer(‘cesiumContainer’, {

infoBox : false,

selectionIndicator : false,

shadows : true,

clockViewModel: new Cesium.ClockViewModel(clock)

});

document.querySelectorAll(’.cesium-timeline-ticLabel’).forEach(function(i) {

i.textContent = i.textContent.replace(“UTC”, “SGT”);

});
