I have a Array Containing Unix time stamps and i want to sort that array any one know how to do it? or maybe converting it to simple date format and then sorting them any way?

Please also give example

I have tried this but didn't work Jquery - Fastest way to sort an array by timestamp

My Code :

//where rawutimes is unsorted unix time array
console.log(rawutimes);


 // output ["1423857905", "1423611874", "1422953913", "1423499856", "1423502234", "1423502884", "1423503754", "1423510832", "1423511445", "1423514134", "1423358619", "1423583825", "1423713297", "1423713401", "1423735601", "1423772523", "1423768351", "1423817039", "1423166917", "1423446473", "1423446761", "1423835014", "1423858124", "1423857905", "1423855048", "1423852400", "1423852313", "1423852210", findIndex: function, find: function]

thesorted = rawutimes.sort(function(x, y){
    return x.timestamp - y.timestamp;
});

//printing the sorted unix time array       
console.log(thesorted);

//Output : ["1423857905", "1423852210", "1422953913", "1423499856", "1423502234", "1423502884", "1423503754", "1423510832", "1423511445", "1423514134", "1423358619", "1423583825", "1423713297", "1423713401", "1423611874", "1423772523", "1423768351", "1423817039", "1423166917", "1423446473", "1423446761", "1423835014", "1423858124", "1423857905", "1423855048", "1423852400", "1423852313", "1423735601", findIndex: function, find: function]

//Converted to Readable date format to confirm if it's sort or not?
rtimes = [];

for (var i = 0; i < rawutimes.length; i++) {
    rtime = timeConverter(thesorted[i]);
    rtimes.push(rtime);
};

• Could you perhaps post the code you tried? It might just be a simple error on your part. – jwang Commented Feb 13, 2015 at 20:01
• [1,2,3].sort(function(a,b){return a-b;}); (numbers are dates are the same as seen from sort() ) – dandavis Commented Feb 13, 2015 at 20:01
• Post your code first what you have tried – Mukesh Agarwal Commented Feb 13, 2015 at 20:06
• I added the code please take a look! – Mary Hempel Commented Feb 13, 2015 at 20:21

Sorted by: Reset to default 10

You have a list of strings, but use .timestamp in the sort function. Just remove it:

rawutimes = ["1423857905", "1423611874", "1422953913", "1423499856", "1423502234", "1423502884", "1423503754", "1423510832", "1423511445", "1423514134", "1423358619", "1423583825", "1423713297", "1423713401", "1423735601", "1423772523", "1423768351", "1423817039", "1423166917", "1423446473", "1423446761", "1423835014", "1423858124", "1423857905", "1423855048", "1423852400", "1423852313", "1423852210"]

thesorted = rawutimes.sort(function(x, y){
    return x - y;
});

rtimes = thesorted.map(function(x) {
  return new Date(x * 1000);
});

document.write(rtimes.join("<br>"))

Try this, perfectly sorted, checked in Chromium browser and Firefox:

var rawutimes = ["1423857905", "1423611874", "1422953913", "1423499856", "1423502234", "1423502884", "1423503754", "1423510832", "1423511445", "1423514134", "1423358619", "1423583825", "1423713297", "1423713401", "1423735601", "1423772523", "1423768351", "1423817039", "1423166917", "1423446473", "1423446761", "1423835014", "1423858124", "1423857905", "1423855048", "1423852400", "1423852313", "1423852210"]
console.log("Raw unix timestamps: " + rawutimes);
var formatted = [];
for (var i = 0; i < rawutimes.length; ++i) {
    var d = new Date(parseInt(rawutimes[i]) * 1000);
    formatted.push(d);
}
thesorted = formatted.sort(function (x, y) {
        return y - x;
        });
console.log("Formatted: " + thesorted);
