How to set time zone in a JSP?

The <fmt:setTimeZone> tag is used to copy a time zone object into the specified scoped variable.

Attribute

The <fmt:setTimeZone> tag has the following attributes −

Attribute	Description	Required	Default
Value	Time zone to expose as a scoped or configuration variable	Yes	None
var	Name of the variable to store the new time zone	No	Replace default
scope	Scope of the variable to store the new time zone	No	Page

Example

<%@ taglib uri = "https://java.sun.com/jsp/jstl/core" prefix = "c" %>
<%@ taglib uri = "https://java.sun.com/jsp/jstl/fmt" prefix = "fmt" %>
<html>
   <head>
      <title>JSTL fmt:setTimeZone Tag</title>
   </head>
   <body>
      <c:set var = "now" value = "<%=new java.util.Date()%>" />
      <p>Date in Current Zone: <fmt:formatDate value = "${now}" type = "both" timeStyle = "long" dateStyle = "long" /></p>
      <p>Change Time Zone to GMT-8</p>
      <fmt:setTimeZone value = "GMT-8" />
      <p>Date in Changed Zone: <fmt:formatDate value = "${now}" type = "both" timeStyle = "long" dateStyle = "long" /></p>
   </body>
</html>

The above code will generate the following result −

Date in Current Zone: 23 September 2010 15:21:37 GST
Change Time Zone to GMT-8
Date in Changed Zone: 23 September 2010 03:21:37 GMT-08:00
