Change Timezone in Tomcat

linux tomcat solr timezone centos

Solution 1

Unless tomcat has a personal TZ environment variable, then it uses /etc/localtime which on my system is a copy of /usr/share/zoneinfo/America/New_York.

Tomcat's personal timezone would be specified in its startup script in a form like:

-Duser.timezone=GMT

Solution 2

Here is what I add at beginning of catalina.sh (after shabang) to change tomcat's timezone:

TOMCAT_TIMEZONE="-Duser.timezone=Europe/Budapest"
CATALINA_OPTS="$CATALINA_OPTS $TOMCAT_TIMEZONE"

And don't forget to restart tomcat to take effect.

Solution 3

As said Eric Wang you may use

TOMCAT_TIMEZONE="-Duser.timezone=Europe/Budapest"
CATALINA_OPTS="$CATALINA_OPTS $TOMCAT_TIMEZONE"

but on CentOS server I didn't find catalina.sh, instead of that I added these variables to /etc/sysconfig/tomcat6, and that's works!

How can I change the timezone in Tomcat? The timezone used by one of the webapps (Solr) is not right (compared to MySQL timestamps), and I think changing Tomcat's timezone will help. Thanks!

  What user is solr running as, and what is its environment set to?

  I loaded solr as a tomcat webapp, and tomcat6 is running as user tomcat. Tomcat6 is running in CentOS 6.3 on port 8080.

The tomcat webapp Solr has its time faster than the time in MySQL/PHP by 4 hours. If tomcat uses /etc/localtime shouldn't the time be the same for Solr and MySQL?

The time last_index_time in DataImporHandler's dataimport.properties is 4 hours ahead of the time used by PHP/MySQL (EDT, America/Newyork). How should I adjust the UTC timezone used by Solr (or Tomcat)

Check any tomcat startup script or config file for CATALINA_OPTS

As @stark answered, pass the -Duser.timezone value when starting Tomcat see this... zeentan.com/wp/apache-solr-timezone-issue

Most posts say CATALINA_OPTS is in catalina.sh, but no such file exist at /usr/share/tomcat6/bin. Where else should I define the timezone? raibledesigns.com/rd/entry/change_tomcat_s_timezone

I had the same issue. It turns out for me Java was looking in the /etc/sysconfig/clock file. This this for comment for more info

Then that's an error on Java's part. /etc/sysconfig/clock is being phased out in recent distros. Everything should be using /etc/localtime unless the user overrides it.

This is not necessarily needed in the catalina.sh, when adding it as a system variable this solution will work as well. :thumbsup:

That works! I have no idea why, but adding the timezone directly to CATALINA_OPTS does not work, but that works! Is TOMCAT_TIMEZONE loaded somewhere else?

@vitormm Nowadays I use timestamp as long, thus timezone doesn't matter much any more in most case. But if you are using spring-boot & embedded tomcat, you may have a try of this: javadeveloperzone.com/spring-boot/…
