How to get local time of different time zones?

Question

I want to get local time of different time zones using Java code. Based on the time zone passed to the function I need that time zone's local time. How to achieve this?

Answer 1

java.util.TimeZone tz = java.util.TimeZone.getTimeZone("GMT+1"); java.util.Calendar c = java.util.Calendar.getInstance(tz);  System.out.println(c.get(java.util.Calendar.HOUR_OF_DAY)+":"+c.get(java.util.Calendar.MINUTE)+":"+c.get(java.util.Calendar.SECOND)); 

Answer 2

I'd encourage you to check out Joda Time, an alternative (but very popular) to the standard Java date and time API:

http://joda-time.sourceforge.net/index.html

Using Joda Time, I think this is what you what:

import org.joda.time.DateTime; import org.joda.time.DateTimeZone;  public class TimeZoneDemo {    public static void main(String[] args) {      DateTime now = new DateTime(System.currentTimeMillis(), DateTimeZone.forID("UTC"));     System.out.println("Current time is: " + now);   } } 

You just need to know the standard ID for the time zone in question, such as UTC.
