/**


*


*


*        There are two ways to make a calculation.  You can use either calculate()   or   add() and subtract()


*        $obj->calculate("month", 2, "add");         is the same as:        $obj->add("month", 2);


*        $obj->calculate("month", 2, "subtract");    is the same as:        $obj->subtract("month", 2);


*


*


*        When using the add() subtract() or calculate() functions, you may provide a unit of time in almost any


*         form imaginable.  


*        Example:  If you want to add 30 seconds to the date/time, you may use any of the following:


*        $obj->add("second", 30);


*        $obj->add("seconds", 30);


*        $obj->add("sec", 30);


*        $obj->add("sec.", 30);


*        $obj->add("secs", 30);


*        $obj->add("secs.", 30);


*        $obj->add("s", 30);


*        $obj->add("s.", 30);


*

//


//    The following is a list of example date/time calculations with this class.


//  You can use many different date/time formats, you only need to provide the mask (as in the php date() function)


//  Currently, d, j, S, D, m, M, n, o, Y, y, a, A, g, G, h, H, i, s     are supported.


//


//    Dates and times without leading zeros will also work too (example:  5/25/08 5:45pm)


//
