Well, at first I wanted to implement a multicalender system for mysql through a variable per column that can be set while creating tables, something like : Create table t0 (dt Date calender jalali) ; but as mysql didn't accept , I worked on some functions.Now, I save iranian Date in Date data type of mysql so why can't i define JDateAdd and JDateDiff for iranian Date ?? Of course you are right , I shouldn't implement all Date functions again but don't we need DateDiff function? Maybe I misunderestood what you are saying , sorry. Regards, Mohsen A.
