Unix timestamp format is common seen when we need to set the date, such as creation date, modification date, available date or expiration date. Very often, we will use the time() function to generate the timestamp, for example, 1209441600.
However, when we design the form for entry or output the result to user, the timestamp format is def. not the one human can read.
To deal with Time Stamp and Date, here is the article I wrote to introduce server side and client side time stamp conversion......

PHP Server Side

In this case, we had a time stamp variable $cdate (Creation Date),  its integer value is 1209441600.
to convert that to date, we do:

<?php echo date("m/d/Y H:i",$cdate);?>

Note that m/d/Y H:i is the format for output, you can certainly change the order to fit what you need.

Very Importantly, uppercase Y will output yyyy, let say 2008. Lowercase y will output yy, let say 08.

JavaScritp Client Side

Sometimes, we might need to convert the timestamp in a form, in that case, a convertion will be needed since JavaScript doesn't has build-in function for that.

Here is the JS function I wrote to handle conversion on both side of Unix timestamp and date:

 
      <Script language="JavaScript" type="text/javascript">
  //The code below is written by Andy Ng<www.pcinvent.info>
  //Please keep the above credit line to the Author
  function stripZeros(input) {
  return input;
  if((input.length > 1) && (input.substr(0,1) == "0")) {
  return input.substr(1);
  } else {
  return input;
  }
  }
  function timestampTodate() {
  var theDate = new Date(document.unixtime2date.unixtimestamp.value * 1000);
  dateString = theDate.toGMTString();
  document.unixtime2date.output.value = dateString;
  }
  function dateToTimeStamp()
  {
  var humDate = new Date(Date.UTC(
  document.date2unixtime.vyy.value,
  (
  stripZeros(document.date2unixtime.vmm.value)-1),
  stripZeros(document.date2unixtime.vdd.value),
  stripZeros(document.date2unixtime.vhh.value),
  stripZeros(document.date2unixtime.vmin.value),
  stripZeros(document.date2unixtime.vsec.value)
  )
  );
  document.date2unixtime.output.value = (humDate.getTime()/1000.0);
  }
  <script>
