public class FormattingTimeZone {
 
  public static void main(String[] args) {
 
    //create Date object
    Date date = new Date();
 
     //formatting TimeZone in z (General time zone) format like EST.
     String strDateFormat = "zzz";
     SimpleDateFormat sdf = new SimpleDateFormat(strDateFormat);
 
     System.out.println("TimeZone in z format : " + sdf.format(date));
 
     //formatting TimeZone in zzzz format Eastern Standard Time.
     strDateFormat = "zzzz";
     sdf = new SimpleDateFormat(strDateFormat);
     System.out.println("TimeZone in zzzz format : " + sdf.format(date));
 
     //formatting TimeZone in Z (RFC 822) format like -8000.
     strDateFormat = "Z";
     sdf = new SimpleDateFormat(strDateFormat);
     System.out.println("TimeZone in Z format : " + sdf.format(date));
  }
}
 
/*
Typical output would be
TimeZone in z format : EST
TimeZone in zzzz format : Eastern Standard Time
TimeZone in Z format : -0500
