Dear Japser, We are using AWS Jasper server (version 6.0.1). The time in Redshift database and Jasper server are both UTC. We'd like to show the time with Australia/Sydney time, so I added Australia/Sydney to the timezone list in applicationContext.xml and restarted tomcat. Then I log onto the web with Australia/Sydney timezone. There is a record, the column created_on is 2015-05-10 23:12:46 (UTC) // Corresponding Sydney time is next day: 2015-05-11 09:12:46. I can see the time is converted to Sydney time if I show the details of this record, but If I use "Group by day" for the this column, the day is "2015-05-10" (should be "2015-05-11" Sydney time). If I use "Group by hour of day", the result is right: 2015-05-11 09 AM. Can you please have a look with priority. Thank you. Regards, Sammy
