Java TimeZone setRawOffset()用法及代碼示例

Java中TimeZone類的setRawOffset(int offsetMillis)方法用於將基本時區偏移量設置為GMT。此偏移值可以是UTC以獲取本地時間。

用法:

public abstract void 
    setRawOffset(int offsetMillis)

參數：該方法接受整數類型的單個參數offsetMillis，該參數指定給定的基準時區與GMT的偏移量。

返回值：該方法不返回任何值。

以下示例程序旨在說明上述函數：
示例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()); 
    } 
}

輸出：

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

示例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("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()); 
    } 
}

輸出：

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