java 中将 RFC1123 日期时间格式化

JDK8 新的日期时间类转换方法:

package com.example;
import org.junit.Test;
import java.time.Instant;
import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;
public class TestRFC1123 {
    String rfc1123Times[] = new String[]
            {
                    "Sat, 08 Jan 2000 18:31:41 GMT",
                    "Wed, 27 Sep 2006 21:36:45 +0200"
            };
    /***
     * jdk 8 new date/time
     */
    @Test
    public void testParse()
    {
        String rfc1123Time;
        for (int i = 0; i < rfc1123Times.length; i++) {
            rfc1123Time = rfc1123Times[i];
            DateTimeFormatter formatter = DateTimeFormatter.RFC_1123_DATE_TIME;
            Instant instant = Instant.from(formatter.parse(rfc1123Time));
            System.out.println("国际时间:"+instant);// 说法可能有错
            ZonedDateTime zdt =
                    ZonedDateTime.parse(
                            rfc1123Time ,
                            DateTimeFormatter.RFC_1123_DATE_TIME
                    );
            ZoneId zone = ZoneId.of( "Asia/Shanghai" );  // Or "Asia/Kolkata", etc.
            ZonedDateTime zdtMontreal = zdt.withZoneSameInstant( zone );
            System.out.println("带时区的时间:"+zdt+", 北京时间:"+zdtMontreal);
        }
    }
}
