Date format conversion error

Question

I am facing the problem while converting the date:

Current format is:Thu Sep 05 12:07:46 IST 2013(dow mon dd hh:mm:ss zzz yyyy)

I need to convert in to:09/04/2013 11:38 PM PDT(mm/dd/yyyy hh:mm a zzz)

But i am not able to convert.

Did you even try using or going through SimpleDateFormatter?! — pranky64, Sep 05 '13 at 07:55
This has been asked a lot just search StackOverflow , to start with take a look at [SimpleDateFormat](http://docs.oracle.com/javase/1.4.2/docs/api/java/text/SimpleDateFormat.html) — AurA, Sep 05 '13 at 07:57

Try using SimpleDateFormatter. You have to tell it the input/output format, you can do that based on this description (you can also find a few common examples there).

The code will be something like this:

try {
    String input = "Thu Sep 05 12:07:46 IST 2013";
    DateFormat formatter = new SimpleDateFormat("I leave this to you :-)))");
    System.out.println(formatter.parse(input));
} catch (ParseException e) {
    e.printStackTrace();
}

Hope that helps.

   try {
          DateFormat dffrom = new SimpleDateFormat("E MMM dd hh:mm:ss zzz yyyy");
          DateFormat dfto = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss a zzz");  
          Date date = dffrom.parse("Thu Sep 05 12:07:46 IST 2013");     
          String s = dfto.format(date);
          System.out.println(s);

        DateFormat dfto = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss a zzz");
        TimeZone zone = TimeZone.getTimeZone("America/Los_Angeles");
        dfto.setTimeZone(zone);
        Date date = dffrom.parse("Thu Sep 05 12:07:46 IST 2013");       
        String s = dfto.format(date);
        System.out.println(s);

Which is not what OP wants. Also code only answer is not really helpful. Care to explain it, specially when your answer is not what is required. – Rohit Jain Sep 05 '13 at 08:31
Can u explain me.. what i did wrong and what he is expecting?.. – Prabhakaran Ramaswamy Sep 05 '13 at 08:34
TimeZone issue. OP wants it in `PDT`, timezone ID for that is `"America/Los_Angeles"`, or `"PST8PDT"`. Apart from that, there is no explanation at all. – Rohit Jain Sep 05 '13 at 08:36
My understanding is he has date with following formate Sep 05 12:07:46 IST 2013 and he need to convert 09/04/2013 11:38 PM PDT – Prabhakaran Ramaswamy Sep 05 '13 at 08:36

You can do this

TimeZone tz = TimeZone.getTimeZone("PST8PDT"); // example
 // required format. Remember M is for month, m for miniute
DateFormat df = new SimpleDateFormat("MM/dd/yyyy hh:mm a zzz");
df.setTimeZone(tz);
String text = df.format(new Date());// current time
System.out.println(text);

Also please check this TimeZones in Java

You try to convert dateformat and timeZone as well, so you need to convert the timezone in your code.

SimpleDateFormat sf = new SimpleDateFormat("dow mon dd hh:mm:ss zzz yyyy");
isoFormat.setTimeZone(TimeZone.getTimeZone("PDT"));
Date date = isoFormat.parse("mm/dd/yyyy hh:mm a zzz");

this may help you.
