How to retrieve user regional settings like language/time zone/calender

Out of the box we only have these two:

forum.appian.com/.../Scripting_Functions.html
forum.appian.com/.../Scripting_Functions.html

If you have enabled "Override user preferences" they'll return the site default settings. That's the expected behavior. At this point you can't retrieve their preferences because by default they are changed to use the default ones. This can even be seen if the user tries to change her preference, she won't be able to do so and it will display the default ones.

If you want to retrieve the user's actual preferences you'll need to create your own custom function:

ServiceContext sc_ = ServiceContextFactory.getServiceContext(username);
UserProfileService usps = ServiceLocator.getUserProfileService(sc_);
UserPreferences upreferencs = usps.getUserPreferences();
return upreferencs.getLocale();

Thanks Eduardo..

Would you mind explaining the use case for this enhancement request? I'm interested in why you need the selected preference for the end user if that won't be taken into account at all due to "Override user preferences".

Basically whatever they selected in the past becomes irrelevant in terms of use because those settings are ignored due to the "Override user preferences flag"
