Convert ISO 8601 time date into plain English
Solution 1
If you really want plain English, why not convert the string to a Date and call date.toLocaleString(), or toUTCString() if you want GMT.
var time=new Date('2010-01-13T18:31:16Z').toLocaleString();
If you want to support IE8 and older browsers you'll need translate the string:
(function(){
var D= new Date('2011-06-02T09:34:29+02:00');
if(!D || +D!==1307000069000){
Date.fromISO= function(s){
var day, tz,
rx=/^(\d{4}\-\d\d\-\d\d([tT][\d:\.]*)?)([zZ]|([+\-])(\d\d):(\d\d))?$/,
p= rx.exec(s) || [];
if(p[1]){
day= p[1].split(/\D/);
for(var i=0,L=day.length;i<L;i++){
day[i]=parseInt(day[i], 10) || 0;
};
day[1]-= 1;
day= new Date(Date.UTC.apply(Date, day));
if(!day.getDate()) return NaN;
if(p[5]){
tz= (parseInt(p[5], 10)*60);
if(p[6]) tz+= parseInt(p[6], 10);
if(p[4]== '+') tz*= -1;
if(tz) day.setUTCMinutes(day.getUTCMinutes()+ tz);
}
return day;
}
return NaN;
}
// shim implemented;
}
else{
Date.fromISO= function(s){
return new Date(s);
}
//native ISO Date implemented;
}
})()
var time= Date.fromISO('2010-01-13T18:31:16Z').toLocaleString();
returned value: (String) Wednesday, January 13, 2010 1:31:16 PM
Solution 2
Take a look at the Date object API in JavaScript: http://www.w3schools.com/jsref/jsref_obj_date.asp. This should get you started:
var timeStr = "2010-01-13T18:31:16Z";
var date = new Date(timeStr);
var day = date.getDate();
var year = date.getFullYear();
var month = date.getMonth()+1;
var dateStr = month+"/"+day+"/"+year;
There are methods to get the time, which you can also append to dateStr.
Solution 3
You can easily change the format with an regex, e.g.
return datestring.replace(/(\d+)-(\d+)-(\d+)T(\d+):(\d+):(\d+)Z/, "$3/$2/$1 $4:$5:$6");
or, you parse the string to a Date
object, and extract the single values (or many more, like the weekday etc):
var date = new Date(datestring); // parses ISO 8601
return date.getDate()+"/"+(date.getMonth()+1)+"/"+date.getFullYear()+" "+…

How can I manipulate a date time in the format below (I believe it is ISO 8601 format) with JavaScript?
2010-01-13T18:31:16Z
I'd like to output as dd/mm/yyyy hh:mm:ss.
Thank you

craft over 5 yearsReading your comments, I briefly wondered why +1 was added to the month as well, but I see it's off the zero index. thx!
