 /**
  * Formats the date in the given format, much like strfmt()
  *
  * This function is used to alleviate the problem with 32-bit numbers for
  * dates pre 1970 or post 2038, as strfmt() has on most systems.
  * Most of the formatting options are compatible.
  *
  * Formatting options:
  * <pre>
  * %a abbreviated weekday name (Sun, Mon, Tue)
  * %A full weekday name (Sunday, Monday, Tuesday)
  * %b abbreviated month name (Jan, Feb, Mar)
  * %B full month name (January, February, March)
  * %d day of month (range 00 to 31)
  * %e day of month, single digit (range 0 to 31)
  * %E number of days since unspecified epoch (integer)
  * (%E is useful for passing a date in a URL as
  * an integer value. Then simply use
  * daysToDate() to convert back to a date.)
  * %j day of year (range 001 to 366)
  * %m month as decimal number (range 1 to 12)
  * %n newline character (\n)
  * %t tab character (\t)
  * %w weekday as decimal (0 = Sunday)
  * %U week number of current year, first sunday as first week
  * %y year as decimal (range 00 to 99)
  * %Y year as decimal including century (range 0000 to 9999)
  * %% literal '%'
  * </pre>
  *
  * @param int $day
  *        	the day of the month
  * @param int $month
  *        	the month
  * @param int $year
  *        	the year. Use the complete year instead of the
  *        	abbreviated version. E.g. use 2005, not 05.
  *        	Do not add leading 0's for years prior to 1000.
  * @param string $format
  *        	the format string
  *        	
  * @return string the date in the desired format
  *        
  * @access public
  * @static
