title: os timezone change tomcat need restart
body: <p>My web application running on Apache Tomcat 7.0. We are calling java util calendar to get the server date-time. The problem is, if the system timezone is changed, the java calendar keeps running with the date-time of the "old" timezone.</p>
  
  <p>JDK used by Tomcat is - JDk1.6</p>
  
  <p>Could you please tell us why tomcat need restart to reflect new timezone?</p>
