Java如何在时区之间转换时间?
package org.nhooo.example.util; import java.util.Calendar; import java.util.GregorianCalendar; import java.util.TimeZone; public class TimeZoneExample { public static void main(String[] args) { //创建一个日历对象并根据本地时间设置时间 //时区 Calendar localTime = Calendar.getInstance(); localTime.set(Calendar.HOUR, 17); localTime.set(Calendar.MINUTE, 15); localTime.set(Calendar.SECOND, 20); int hour = localTime.get(Calendar.HOUR); int minute = localTime.get(Calendar.MINUTE); int second = localTime.get(Calendar.SECOND); //打印当地时间 System.out.printf("Local time : %02d:%02d:%02dn", hour, minute, second); //创建一个表示德国时区的日历对象。然后我们 //用当地时间的值弄湿日历的时间 Calendar germanyTime = new GregorianCalendar(TimeZone.getTimeZone("Germany")); germanyTime.setTimeInMillis(localTime.getTimeInMillis()); hour = germanyTime.get(Calendar.HOUR); minute = germanyTime.get(Calendar.MINUTE); second = germanyTime.get(Calendar.SECOND); //打印当地时间 in Germany time zone System.out.printf("Germany time: %02d:%02d:%02dn", hour, minute, second); } }
