这段代码在我正在开发的应用程序中很有帮助:

    Instant date = null;
    Date sdf = null;
    String formatTemplate = "EEE MMM dd yyyy HH:mm:ss";
    try {
        SimpleDateFormat isoFormat = new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss");
        isoFormat.setTimeZone(TimeZone.getTimeZone(ZoneId.of("US/Pacific")));
        sdf = isoFormat.parse(timeAtWhichToMakeAvailable);
        date = sdf.toInstant();

    } catch (Exception e) {
        System.out.println("did not parse: " + timeAtWhichToMakeAvailable);
    }

    LOGGER.info("timeAtWhichToMakeAvailable: " + timeAtWhichToMakeAvailable);
    LOGGER.info("sdf: " + sdf);
    LOGGER.info("parsed to: " + date);

calendar是使用JDK类处理时区的常用方法。Apache Commons还有一些可能有用的替代方案/实用程序。Edit Spong的留言提醒我，我听说Joda-Time真的很不错(尽管我自己没有用过)。

您还可以在JVM级别设置时区

Date date1 = new Date();
System.out.println(date1);

TimeZone.setDefault(TimeZone.getTimeZone("UTC"));
// or pass in a command line arg: -Duser.timezone="UTC"

Date date2 = new Date();
System.out.println(date2);

输出:

Thu Sep 05 10:11:12 EDT 2013
Thu Sep 05 14:11:12 UTC 2013

这个答案可能是最短的，它只使用Date类:

long current = new Date().getTime() + 3_600_000;              //e.g. your JVM time zone +1 hour (3600000 milliseconds)
System.out.printf("%1$td.%1$tm.%1$tY %1$tH:%1$tM\n", current);//european time format

但是，如果可以的话，用更现代的方式来做同样的事情。

package org.example;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;

public class time {
   public static void main(String[] args) {
       SimpleDateFormat sdf=new SimpleDateFormat("yyyy/MM/dd HH:mm");
       sdf.setTimeZone(TimeZone.getTimeZone("Asia/Jakarta"));
       Date date=new Date();
       sdf.format(date);
       System.out.println(sdf.format(date));
   }
}

这段代码在我正在开发的应用程序中很有帮助:

    Instant date = null;
    Date sdf = null;
    String formatTemplate = "EEE MMM dd yyyy HH:mm:ss";
    try {
        SimpleDateFormat isoFormat = new SimpleDateFormat("EEE MMM dd yyyy HH:mm:ss");
        isoFormat.setTimeZone(TimeZone.getTimeZone(ZoneId.of("US/Pacific")));
        sdf = isoFormat.parse(timeAtWhichToMakeAvailable);
        date = sdf.toInstant();

    } catch (Exception e) {
        System.out.println("did not parse: " + timeAtWhichToMakeAvailable);
    }

    LOGGER.info("timeAtWhichToMakeAvailable: " + timeAtWhichToMakeAvailable);
    LOGGER.info("sdf: " + sdf);
    LOGGER.info("parsed to: " + date);
