Problem showing date

[Javier Tom�]

Hi, I'm been working in a Servlet that make a page and, in this page I`m showing the date of the day using this code:    DateFormat df = DateFormat.getInstance();  String zone = "GMT-4:00";  TimeZone tz = TimeZone.getTimeZone("America/La_Paz");  df.setTimeZone(tz);  java.util.Date date = new java.util.Date();   for printing the date I'm using:   df.format(date)   My problem is this, no matters wich string for "zone" I use, it allways displays the same time, and I want the time of my country (VENEZUELA), Windows call my Time Zone Caracas/La Paz. Does anybody knows why this code is not showing me my time?   Thank you very much...   Javier Tom�
