Java TimeZone setRawOffset()方法及示例

Java中 TimeZone类 的 setRawOffset(int offsetMillis) 方法用于设置基础时区与GMT的偏移。该偏移值可用于UTC，以获得本地时间。

语法

public abstract void 
    setRawOffset(int _offsetMillis_ )

参数： 该方法接受一个整数类型的参数offsetMillis ，指定给定的基础时区与GMT的偏移。
返回值： 该方法不返回任何值。下面的程序说明了上述函数：

程序1 :

// 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

程序2

// 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("Initially 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

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