date conversion and math in actionscript 3.0

I have two values coming in, a string in the form StartTime YYYY-MM-DD HH:MM:SS and a Duration in the form HH:MM:SS. from these two values I need to determine the endTime and put it in the same format as the StartTime.

I have tried to make something like

startTimeArray:Array = StartTime.split(/[ -:]/);
var date:Date = new Date(startTimeArray[0], startTimeArray[1]-1, startTimeArray[2], startTimeArray[3], startTimeArray[4], startTimeArray[5] );

but the split of course results in strings and not numbers and I can't figure how to convert all these sections of the time into numbers, and following that I do not see a way to apply math by adding the Duration Date object to the StartTime Date object if I am able to get them properly converted.

Am I going down a good path here? if so, how can I convert an array o开发者_C百科f strings to numbers and how can I add the duration to starttime? Thanks

const start:String = "2011-04-03 01:39:48";
const startArray:Array = start.split(/[: -]/g);
var startDate:Date = new Date(
    startArray[0], startArray[1]-1, startArray[2],
    startArray[3], startArray[4], startArray[5]
);
const duration:String = "02:10:10";
const durationArray:Array = duration.split(/:/g);
var durationDate:Date = new Date();
durationDate.setTime(
    durationArray[0] * 3600000 + /* hour = 60m * 60s * 1000ms */
    durationArray[1] * 60000 + /* minute = 60s * 1000ms */
    durationArray[2] * 1000 /* second = 1000ms */
);
var finalDate:Date = new Date();
finalDate.setTime(startDate.time + durationDate.time);
trace(startDate);
trace(durationDate.time);
trace(finalDate);

Outputs:

Sun Apr 3 01:39:48 GMT-0300 2011
7810000
Sun Apr 3 03:49:58 GMT-0300 2011

You will want to split the date and time first and then work from there with the arrays.

var date_:String = StartTime.substring(0,StartTimet.indexOf(" "));
var time_:String = StartTime.substring(StartTime.indexOf(" ")+1, StartTime.length);
trace(date_); // YYYY-MM-DD
trace(time_); // HH:MM:SS

Then split your date into an array

var date_array:Array = StartTime.split("-");

Cast the elements of the array with Number

Then do the same for time but use ":" for the split.
Duration can be split the same way. Then just use normal addition after casting.

var d:Date = new Date(year,month,date,hour,minutes,seconds);
var d_added:Date = new Date(year,month,date,hour+duration_hour,
              minutes+duration_minutes,seconds+duration_seconds);
