Print out a nicely formatted timestamp in JavaScript.

timestamp.js

/**
 * Return a timestamp with the format "m/d/yy h:MM:ss TT"
 * @type {Date}
 */

function timeStamp() {
// Create a date object with the current time
  var now = new Date();

// Create an array with the current month, day and time
  var date = [ now.getMonth() + 1, now.getDate(), now.getFullYear() ];

// Create an array with the current hour, minute and second
  var time = [ now.getHours(), now.getMinutes(), now.getSeconds() ];

// Determine AM or PM suffix based on the hour
  var suffix = ( time[0] < 12 ) ? "AM" : "PM";

// Convert hour from military time
  time[0] = ( time[0] < 12 ) ? time[0] : time[0] - 12;

// If hour is 0, set it to 12
  time[0] = time[0] || 12;

// If seconds and minutes are less than 10, add a zero
  for ( var i = 1; i < 3; i++ ) {
    if ( time[i] < 10 ) {
      time[i] = "0" + time[i];
    }
  }

// Return the formatted string
  return date.join("/") + " " + time.join(":") + " " + suffix;
}

Greetings, a more complete function using a more complete String replace function, use: mf("Y-M-D H:I:S")
Y=Complete Year
y=Two digits year
M=Month
D=Date
H:Hour
h:12 hour format
I: minutes
S:seconds
x:am/pm

function mf(formato){ var hor,hor2,x; var fechai=new Date(); var ano=fechai.getYear()+1900; var ano2=(""+(fechai.getYear()+1900)).slice(-2); var mes=("0"+(fechai.getMonth()+1)).slice(-2); var dia=("0"+fechai.getDate()).slice(-2); hor=hor2=("0"+fechai.getHours()).slice(-2); if(fechai.getHours()>12){ hor2=fechai.getHours()-12; x="pm"; }else{ x="am"; } var min=("0"+fechai.getMinutes()).slice(-2); var seg=("0"+fechai.getSeconds()).slice(-2); var fecha=formato.reemplaza("YyMDHhISx".split(''),[ano,ano2,mes,dia,hor,hor2,min,seg,x]); alert(fecha); } String.prototype.reemplaza=function(busca,reemplaza){ var b=Array.isArray(busca); var r=Array.isArray(reemplaza); var ret=this; if(b){ for(var i in busca){ var c=r?(reemplaza[i]?reemplaza[i]:""):reemplaza; ret=ret.replace(new RegExp(busca[i],'g'),c); } }else{ var c=r?reemplaza[0]:reemplaza; ret=ret.replace(new RegExp(busca,'g'),c); } return ret; }

Thanks a lot!

cool, thanks for sharing your example!
