Convert ISO 8601 time dates to plain English

Question

How can I manipulate date time in the format below (I believe this is the ISO 8601 format) with JavaScript?

2010-01-13T18: 31: 16Z

I would like to output as dd / mm / yyyy hh: mm: ss.

thanks

Answer 1

If you really need plain English, why not convert the string to 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 browsers IE8 and older, you will need to translate the line:

(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 ();

return value: (String) January 13, 2010 1:31:16

Answer 2

Take a look at the Date object API in JavaScript: http://www.w3schools.com/jsref/jsref_obj_date.asp . This should start:

 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 for getting time, which you can also add to dateStr.

You can easily change the format with a regular expression, for example

 return datestring.replace(/(\d+)-(\d+)-(\d+)T(\d+):(\d+):(\d+)Z/, "$3/$2/$1 $4:$5:$6"); 

or you parse a string into a Date object and extract single values ​​(or many others, for example, day of the week, etc.),

 var date = new Date(datestring); // parses ISO 8601 return date.getDate()+"/"+(date.getMonth()+1)+"/"+date.getFullYear()+" "+…
