Java 中的 TimeZone setRawOffset()方法，示例

原文:https://www . geesforgeks . org/time zone-setrawpoffset-method-in-Java-with-examples/

Java 中 时区类 的set raw offset(intoffset millis)方法用于将基准时区偏移量设置为 GMT。该偏移值可以是世界协调时，以获得当地时间。

语法:

public abstract void 
    setRawOffset(int *offsetMillis*)

参数:该方法接受整数类型的单个参数偏移量，该参数指定给定的基准时区相对于格林尼治标准时间的偏移量。

返回值:该方法不返回值。

下面的程序说明了上述功能: 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());
    }
}

Output:

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("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());
    }
}

Output:

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