Pointing tomcat to a different timezone
Dear Tomcat Users, I am deploying a Java Application in Tomcat, that is picking the wrong Time-zone from OS. I did try to change the time settings at OS level. while the OS is PDT [root@sdc-cidev10 ~]# date Sun Jul 29 15:16:41 PDT 2012 My Java App is still in Universal Time-zone. Can you please guide me on how to set -Duser.timezone property for Tomcat? Thanks in advance, Krishna Chaitanya

String timeZoneId = Australia/Sydney; TimeZone timeZone = TimeZone.getTimeZone(timeZoneId); Is this Sun Oracle Java? Do you have the tzdata package installed?
Re: Pointing tomcat to a different timezone
Hello Igor Thanks for your response :) Request some more info to get started .. Yes, I am using sun jdk 1.6 ... how do i verify installation of tzdata package? thanks, Krishna Chaitanya On Sun, Jul 29, 2012 at 5:19 PM, Igor Cicimov icici...@gmail.com wrote: On Mon, Jul 30, 2012 at 8:39 AM, krishna chaitanya kurnala kkc...@gmail.com wrote: Dear Tomcat Users, I am deploying a Java Application in Tomcat, that is picking the wrong Time-zone from OS.

Hello Konstantin I verified the timezone is same for both users: [jenkinspan@sdc-cidev10 ~]$ date Sun Jul 29 17:31:27 PDT 2012 [jenkinspan@sdc-cidev10 ~]$ sudo su - root [root@sdc-cidev10 ~]# date Sun Jul 29 17:31:39 PDT 2012 We are using apache-tomcat-6.0.33 I didnot do anything special but, untar and ./startup.sh from bin folder.
