Support for different calendars other that Gregorian (such as Jalali Calendar) is needed. There should be a way to add different calendars to this module because different locales may need a calendar other that the default Gregorian. Also date and time formats should be configurable for each locale and for each calendar!

I think Unix timestamps can help for supporting calendars. If there would be a infrastructure for adding calendars, developers would help to add actual calendars.

I hadn't thought about different calendar systems yet, but we definitely need different date-formats for different locales.
That means localizing the entries in admin/settings/date-time and maybe some magic for cck date and datestamp fields, which is probably the harder part ...

Yes, but I think if calendar system is designed first, it will make adding date-formats later easier.

I think that user must be able to add calendars from a list of calendars, or just giving it a title, and somehow giving it the formula to calculate the date passed to it, based on a time stamp.

Then, each calendar can have date-formats, like long, medium, and short, which user can select from or enter the pattern.

CLDR has some info about calendars, and they are already localized. Maybe they can help here.
