Timezone settings in Liferay 6.1

[11年前 に Ratnamala Mehetre によって更新されました。]

For one of my Calendar portlet and Message board portlet timezone related issues, I figured out timezone settings at below three levels.
Env: Liferay 6.1 CE/EE with Bundled tomcat

1. On Liferay/tomcat level
..\liferay-portal-6.1.10-ee-ga1\tomcat-7.0.25\bin\setenv.bat
with following property:
-Duser.timezone= (Set proper timezone here)

2. Portal level:
Go to Control Panel> Portal > Portal Settings > Look for Display Settings > Select proper timezone and save it.

3. User Level:
Go to Control Panel> Portal > Users and Organizations > select User > Look for Display Settings > Select proper timezone and save it.

What is the recommended way to do timezone settings in Liferay 6.1?

At the user level if there are users accessing from different timezones.
