JavaScript datetime parsing [duplicate]

Answer 1

function dateFromString(str) {
  var m = str.match(/(\d+)-(\d+)-(\d+)\s+(\d+):(\d+):(\d+)\.(\d+)/);
  return new Date(+m[1], +m[2] - 1, +m[3], +m[4], +m[5], +m[6] * 100);
}

dateFromString(myArr[0][0]); // Sat Oct 10 2012 03:47:00 GMT-0500 (EST)

Answer 2

Try the following:

new Date(Date.parse(myArr[0][0]));

EXAMPLE

Use the Date.parse method to parse the string into the number of milliseconds since January 1, 1970, 00:00:00 UTC. Take that number of milliseconds and call the Date method once again to turn that time into a date object.

EDIT:

Well this may be a little ugly for this case, but it seems Firefox is having an issue with the -s and the 00.0.

var myArr = [["2012-10-10 03:47:00.0", 23.400000000000002], ["2012-10-10 03:52:00.0", 23.3]];

var date = convertDateTime(myArr[0][0]);
console.log(date);

function convertDateTime(dateTime){
    dateTime = myArr[0][0].split(" ");

    var date = dateTime[0].split("-");
    var yyyy = date[0];
    var mm = date[1]-1;
    var dd = date[2];

    var time = dateTime[1].split(":");
    var h = time[0];
    var m = time[1];
    var s = parseInt(time[2]); //get rid of that 00.0;

    return new Date(yyyy,mm,dd,h,m,s);
}
