在JavaScript中以Hours24:Minutes:Seconds格式获取当前UTC时间

在JavaScript中获取当前UTC时间 (Getting current UTC time in JavaScript)

To get the current UTC time in JavaScript, we need to use three library functions of Date class,

要使用JavaScript获取当前UTC时间 ,我们需要使用Date类的三个库函数,

  1. Date getUTCHours() Method – It returns current UTC hours

    Date getUTCHours()方法 –返回当前UTC时间

  2. Date getUTCMinutes() Method – It returns current UTC minutes

    Date getUTCMinutes()方法 –返回当前UTC分钟

  3. Date getUTCSeconds() Method – It returns current UTC seconds

    Date getUTCSeconds()方法 –返回当前UTC秒

Note: To call these functions, we need to create an object to the Date class using Date class constructor.

注意:要调用这些函数,我们需要使用Date类的构造函数为Date类创建一个对象。

Examples:

例子:

    Date class constructor:
    var dt = new Date();

    Function calls:
    dt.getUTCHours();
    dt.getUTCMinues();
    dt.getUTCSeconds();
    
    Output:
    18
    22
    38
