public class Miracle01 { private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS" ); private static SimpleDateFormat sdfutc = new SimpleDateFormat(" yyyy-MM-dd'T'HH:mm:ss.SSS'Z' " ); public static void main(String[] args) { dateToUtc( new Date()); public static void dateToUtc(Date date) { sdfutc.setTimeZone( TimeZone.getTimeZone( "UTC" ) );
// sdfutc.setTimeZone( TimeZone.getTimeZone("GMT") ); System.out.println( "北京时间: " + sdf.format(date)); System.out.println( "UTC时间: " + sdfutc.format(date));

运行结果如下:

北京时间: 2021-11-25 20:19:27.547
UTC时间: 2021-11-25T12:19:27.547Z

2)方式2

代码 实现 如下:

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
 * @author Miracle Luna
 * @date 2021/11/25
public class Miracle02 {
    private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
    private static SimpleDateFormat sdfutc = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX");
    public static void main(String[] args) {
        dateToUtc(new Date());
    public static void dateToUtc(Date date) {
     sdfutc.setTimeZone(TimeZone.getTimeZone("UTC"));
// sdfutc.setTimeZone(TimeZone.getTimeZone("GMT")); System.out.println("北京时间: " + sdf.format(date)); System.out.println("UTC时间: " + sdfutc.format(date));

运行结果如下:

北京时间: 2021-11-25 20:26:20.153
UTC时间: 2021-11-25T12:26:20.153Z

2、UTC格式:2021-11-25T12:30:29.656+00:00

代码实现如下:

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
 * @author Miracle Luna
 * @date 2021/11/25
public class Miracle03 {
    private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
    private static SimpleDateFormat sdfutc = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSz");
    public static void main(String[] args) {
        dateToUtc(new Date());
    public static void dateToUtc(Date date) {
        sdfutc.setTimeZone(TimeZone.getTimeZone("GMT+00:00"));
        System.out.println("北京时间: " + sdf.format(date));
        System.out.println("UTC时间: " + sdfutc.format(date).replace("GMT", ""));

运行结果如下:

北京时间: 2021-11-25 20:30:29.656
UTC时间: 2021-11-25T12:30:29.656+00:00

3、UTC格式:2021-11-25T12:33:02.000+00:00

代码实现如下:

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
 * @author Miracle Luna
 * @date 2021/11/25
public class Miracle04 {
    private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    private static SimpleDateFormat sdfutc = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.000z");
    public static void main(String[] args) {
        dateToUtc(new Date());
    public static void dateToUtc(Date date) {
        sdfutc.setTimeZone(TimeZone.getTimeZone("GMT+00:00"));
        System.out.println("北京时间: " + sdf.format(date));
        System.out.println("UTC时间: " + sdfutc.format(date).replace("GMT", ""));

运行结果如下:

北京时间: 2021-11-25 20:33:02
UTC时间: 2021-11-25T12:33:02.000+00:00

4、UTC格式:2021-11-25T12:45:39.119+0000

代码实现如下:

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;
 * @author Miracle Luna
 * @date 2021/11/25
public class Miracle05 {
    private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    private static SimpleDateFormat sdfutc = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
    public static void main(String[] args) {
        dateToUtc(new Date());
    public static void dateToUtc(Date date) {
        sdfutc.setTimeZone(TimeZone.getTimeZone("UTC"));
//        sdfutc.setTimeZone(TimeZone.getTimeZone("GMT"));
        System.out.println("北京时间: " + sdf.format(date));
        System.out.println("UTC时间: " + sdfutc.format(date));

运行结果如下:

北京时间: 2021-11-25 20:47:12
UTC时间: 2021-11-25T12:47:12.674+0000
