datenow is 12 pm. why after convert it's "Mon Sep 17 00:18:23 GMT+07:00 2012"

Can you help me? Thanks.

Answer 1

Because hh in hours grabs hours from 1 to 12 you can see the encoding here . You should be using:

DateFormat formatter = new SimpleDateFormat("yyyyMMddHHmmss");
String datenow="20120917121823";
Date date2 = (Date) formatter.parse(datenow);

Answer 2

You can use:

SimpleDateFormat formatter = new SimpleDateFormat("EEE MMM dd HH:mm:ss zzzz yyyy");
    try {
        String temp = "Mon Sep 17 00:18:23 GMT+07:00 2012";
        Date expiry = formatter.parse(temp);
    } catch (Exception e) {
        e.printStackTrace();
    }
