一些例子

import java.util.Calendar;

import java.util.GregorianCalendar;

import java.util.TimeZone;

public class TimeZoneExample {

public static void main(String[] args) {

// Create a calendar object and set it time based on the local

// time zone

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);

// Print the local time

System.out.printf("Local time : %02d:%02d:%02d\n", hour, minute, second);

// Create a calendar object for representing a Germany time zone. Then we

// wet the time of the calendar with the value of the local time

Calendar germanyTime = new GregorianCalendar(TimeZone.getTimeZone("Europe/Berlin"));

germanyTime.setTimeInMillis(localTime.getTimeInMillis());

hour = germanyTime.get(Calendar.HOUR);

minute = germanyTime.get(Calendar.MINUTE);

second = germanyTime.get(Calendar.SECOND);

// Print the local time in Germany time zone

System.out.printf("Germany time: %02d:%02d:%02d\n", hour, minute, second);

}

}
