[Evolution] Alternative Calendar

["Amir Reza Khosroshahi" <amir khosroshahi gmail com>]

Hi every body,

I had a question about Evolution's calendars. Is it possible to make Evolution a calendar other than the default Gregorian calendar?
Of course I know everything is possible by hacking the code, but I'm looking for the easiest way.
To be specific, I want to use Persian (Jalali) calendar on Evolution.

Thanks a lot
