	      o $timestamp
		- The optional $timestamp parameter is an integer Unix timestamp that defaults to the current local time if a  $timestamp  is  not
		given. In other words, it defaults to the value of time(3).

RETURN VALUES

	Returns an integer.

	As  idate(3) always returns an integer and as they can't start with a "0", idate(3) may return fewer digits than you would expect. See the
       example below.

ERRORS
/EXCEPTIONS
	Every call to a date/time function will generate a E_NOTICE if the time zone is not valid, and/or a E_STRICT or E_WARNING message if using
       the system settings or the $TZ environment variable. See also date_default_timezone_set(3)

EXAMPLES

       Example #1

	      idate(3) example

	      <?php
	      $timestamp = strtotime('1st January 2004'); //1072915200

	      // this prints the year in a two digit format
	      // however, as this would start with a "0", it
	      // only prints "4"
	      echo idate('y', $timestamp);
	      ?>
