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，
Date getUTCHours() Method – It returns current UTC hours
Date getUTCHours()方法 –返回当前UTC时间
Date getUTCMinutes() Method – It returns current UTC minutes
Date getUTCMinutes()方法 –返回当前UTC分钟
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
