This is not a question but an answer to one which a number of people have asked: namely how to localise reports in Jasper Server with respect to time zone
I have written a wiki page about it. I can't seem to link directly to it here, but if you go to the wiki, click How-To in the common searches and then search for time zone localization you should find it
Hope it is useful
Just a small note that can help other people reading the article posted above. Under the section 3. Setting the user’s time zone it is written following by the author:
"The value provided here gets set as the REPORT_TIME_ZONE parameter.
It might be possible to set the user’s time zone when logging in via some SSO mechanism but I have not investigated this."
If you are making the build yourself from the source code, you can override it from file jasperreports.properties located under: jasperserver\jasperserver-war\src\main\webappAdditions\WEB-INF\classes.
Just uncomment last line property net.sf.jasperreports.jdbc.time.zone and set your time zone instead of REPORT_TIME_ZONE value (use quotes to ensure unescaping):
