What is the format of this timestamp? 2015-02-25T15:03:57+0000

I tried this:

"dd-MM-yy'T':HH:mm:SSZ"

But Im getting

java.text.ParseException: Unparseable date: "2015-02-25T15:06:38+0000" (at offset 11)

This is my code:

  SimpleDateFormat format = new SimpleDateFormat(Preferences.SERVER_TIMESTAMP_FORMAT);
        Date date = null;
        try {
            date = format.parse(serverTimestamp);
            return date.getTime();
        } catch (ParseException e) {
            e.printStackTrace();
            return 0;
        }

Try "yyyy-MM-dd'T'HH:mm:ssZ":

• Put the year first
• Remove the colon after the T
• Use seconds instead of milliseconds.
