Java中的 TimeZone setRawOffset() 方法及示例

Java中TimeZone 类的setRawOffset(int offsetMillis )方法用于将基准时区偏移设置为 GMT。这个偏移值可以到 UTC 来获取本地时间。

句法：

public abstract void 
    setRawOffset(int offsetMillis)

参数：该方法接受一个整数类型的参数offsetMillis ，它指定给定的基准时区偏移量到 GMT。

返回值：该方法不返回任何值。

下面的程序说明了上述函数：
方案一：

// Program to demonstrate the
// setRawOffset()
  
import java.util.*;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // Create time zone object
        TimeZone obj
            = TimeZone.getTimeZone("Pacific/Pago_Pago");
  
        // Printing RawOffset value
        System.out.println("Initially RawOffset is = "
                           + obj.getRawOffset());
  
        // Setting RawOffset on object obj
        obj.setRawOffset(6000000);
        System.out.println("RawOffset "
                           + "set to 6000000");
  
        // Printing RawOffset value
        System.out.println("Current RawOffset is = "
                           + obj.getRawOffset());
    }
}

输出：

Initially RawOffset is = -39600000
RawOffset set to 6000000
Current RawOffset is = 6000000

方案二：

// Program to demonstrate the
// setRawOffset()
  
import java.util.*;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // Create time zone object
        TimeZone obj
            = TimeZone.getTimeZone("Europe/Rome");
  
        // Printing RawOffset value
        System.out.println("Inittally RawOffset is = "
                           + obj.getRawOffset());
  
        // Setting RawOffset on object obj
        obj.setRawOffset(8000000);
        System.out.println("RawOffset "
                           + "set to 8000000");
  
        // Printing RawOffset value
        System.out.println("Current RawOffset is = "
                           + obj.getRawOffset());
    }
}

输出：

Inittally RawOffset is = 3600000
RawOffset set to 8000000
Current RawOffset is = 8000000
