LinuxQuestions.org - EST of Australian timezone does not work

Double check your calendar. April 3, 2011 is a Sunday. Ay.

Sat Apr 02 07:23:31 EST 2011 Eastern Summer Time (Victoria)
Sun Apr 03 06:23:31 EST 2011 Eastern Standard Time (Victoria)

Or double check your code.

Here's a simple Java Code on timezone (sorry it's messy)

Code:

import java.util.*;

import java.text.DateFormat;

import java.text.SimpleDateFormat; 

import java.util.Calendar;                                            

import java.util.Date;

class TimesAX

{

public static void main(String[] args)

{

int daysPast=202;    //insert days past



String sp="";

Date date = new Date();

Calendar calVictoria = Calendar.getInstance();

calVictoria.setTimeZone(TimeZone.getTimeZone("Australia/Victoria")); 

TimeZone AusTZ = calVictoria.getTimeZone();

  String tzAName =

      AusTZ.getDisplayName(AusTZ.inDaylightTime(date), TimeZone.LONG);

  String tzANameSt =

      AusTZ.getDisplayName(AusTZ.inDaylightTime(date), TimeZone.SHORT);



  System.out.println("Time in Victoria: " + calVictoria.get(Calendar.HOUR_OF_DAY) + ":"

            +sp+ calVictoria.get(Calendar.MINUTE)

            +" tz "+ tzANameSt +" "+tzAName);

  



      System.out.print("\n"); 



TimeZone.setDefault(AusTZ);

Date AusDate = Calendar.getInstance(AusTZ).getTime();                  

System.out.println(AusDate);                                        

                                                                      

 DateFormat format17 =                                                  

 new SimpleDateFormat("EEEE-MMMM-dd-yyyy  h:mm a zz  Z");              

 System.out.println(format17.format(AusDate));

  System.out.println("180 days future      "+getDateAfterDays(180));

 

String tzAName2 =

      AusTZ.getDisplayName(AusTZ.inDaylightTime(getDateBeforeDays((daysPast+1))), TimeZone.LONG);

String tzAName3 =

      AusTZ.getDisplayName(AusTZ.inDaylightTime(getDateBeforeDays((daysPast))), TimeZone.LONG);



  System.out.println((daysPast+1)+" days past      "

    +getDateBeforeDays((daysPast+1)) +" "+tzAName2);

  System.out.println(daysPast+" days past      "

    +getDateBeforeDays(daysPast)+" "+tzAName3);



}

public static Date getDateAfterDays(int days) {  

 long backDateMS = System.currentTimeMillis() + ((long)days) *24*60*60*1000;  

 Date backDate = new Date();  

 backDate.setTime(backDateMS);  

 return backDate;  

 } 

public static Date getDateBeforeDays(int days) {  

 long backDateMS = System.currentTimeMillis() - ((long)days) *24*60*60*1000;  

 Date backDate = new Date();  

 backDate.setTime(backDateMS);  

 return backDate;  

 } 

}

Though, you might want to rewrite to new acronyms.
