Question

在cesium中，默认时区为UTC。所以我想将UTC时区更改为SGT时区....你可以纠正我的错误，我的代码在下面找到.. SGT时区是GMT + 8 ..我想在时间轴和时钟视图上看到新加坡时间...我还希望将UTC替换为SGT。这是我的代码

    document.querySelectorAll('.cesium-timeline-ticLabel').forEach(function(i) {
    i.textContent = i.textContent.replace("UTC", "SGT");
    });

默认时区是UTC，因此我想更改为GMT +8

的SGT时区

在Cesiumjs中将UTC时区更改为SGT时区
