getTimestamp方法返回当前时间的时间戳。

语法

Cesium.getTimestamp()

返回值

Number ：返回表示当前时间的时间戳。

示例

var currentTime = Cesium.getTimestamp();
console.log(currentTime); // 输出当前时间的时间戳

说明

Cesium的时间戳是指从1970年1月1日UTC时间00:00:00起至当前时间所经过的秒数，即Unix时间戳。在Cesium中，它是以JavaScript的Date对象所表示的UTC时间为基础计算的。Cesium中有一些内置的API（例如Clock）会使用到时间戳，因此该API有时会被用来获取Cesium时间的一个快速、简单和精确的方法。
