答案// Create a new JavaScript Date object based on the timestamp // multiplied by 1000 so that the argument is in milliseconds, not seconds. var date = new Date(unix_timestamp*1000); // Hours part from the timestamp var hours = date.getHours(); // Minutes part from the timestamp ...

该方法可用于将日期与毫秒进行比较。请务必记住,它会在日期之间执行数值比较,并返回自 1970 年 1 月 1 日以来的时间值。getTime()``getTime() // Create two Date objectsconstfirstDate =newDate('2025-01-01');constsecondDate =newDate('2024-01-02');// Get the time in milliseconds for each da...
The JavaScriptDateobject provides several methods to manipulate date and time. You can get the current timestamp by calling thenow()function on theDateobject like below: consttimestamp=Date.now() This method returns the current UTC timestamp in milliseconds. TheDate.now()function works in almost...
Gets the Unix timestamp from aDateobject. UseDate.prototype.getTime()to get the timestamp in milliseconds and divide by1000to get the timestamp in seconds. UseMath.floor()to appropriately round the resulting timestamp to an integer.
// 1556372741848, _milliseconds_ since Jan 1 1970Date.now();// 1556372741, _seconds_ since Jan 1, 1970. This is the Unix timestampMath.floor(Date.now()/1000); 给定一个现有日期,您可以使用getTime()函数或valueOf()函数获取自 1970 年 1 月 1 日以来的毫秒数。这两个函数是等价的。
以下是一个示例代码,展示如何获取纳秒级的Unix时间戳: 代码语言:txt 复制 function getNanoTimestamp() { const performanceTimestamp = performance.now(); // 获取高精度时间戳(以秒为单位,包含小数部分) const milliseconds = new Date().getTime(); // 获取当前时间的毫秒数 const nanoSeconds = performance...
