get user logged in country time zone and set it as default value for param on selection screen?

[raja_ravichandran]

Based on user logged in country we should set default value for the parameter on selection screen(Logged in country time zone(tzone)? For example If the user logged in from japan it should set the default value as JAPAN like the same for other countries also. How to achieve this? Any suggestions would be helpful. Thanks in advance..

What is the context? Dates are usually in the time zone of the system. Only a few features take the time zone into account.

User accounts can have a personal time zone. Make sure that's set properly, and then read it to populate your parameter.
