MXコンポーネント用のものは見つかりましたが、sparkコンポーネントで動作することはできません。

現在の日付と日付をラベルに表示したいだけです。

これを試しましたが（コードを参照）、関数Function（）{}しか返されません。

これを変える：

// offset is today +/- a set number of days
// displayDate(-1) returns string for yesterday
// displayDate(1) returns string for tomorrow etc
public function displayDate(offset:int=0):String {
    var formattedString:String;

    var now:Date = new Date();
    var day_int:int = now.getDate() + offset; //gets day of the month
    var month_int:int = (now.getMonth()+1); // gets month. Months are given from 0 to 11, so you need to do +1 here
    var year_int:int = now.getFullYear(); // gets year

    var day_string:String;
    //display always 2 digits for a month, so '02' instead of just '2' for February
    if (day_int < 10) {
        day_string = "0" + day_int.toString();
    }
    else {
        day_string = day_int.toString();
    }

    var month_string:String;
    //display always 2 digits for a day, so '02' instead of just '2'
    if (month_int < 10) { 
        month_string = "0" + month_int.toString();
    }
    else {
        month_string = month_int.toString();
    }

    var year_string:String = year_int.toString();

    formattedString = day_string + "/" + month_string + "/" + year_string;

    return formattedString;
}

mxmlでは、次のように使用します。

<s:Label text="{ displayDate(-3) }" />
