     These functions allow you to get the date and time from the server
     where your PHP scripts are running. You can use these functions to format the
     date and time in many different ways.

    <note>
     <simpara>
      Please keep in mind that these functions are dependent on
      the locale settings of your server. Make sure to take
      daylight saving time (use e.g.
      <literal>$date = strtotime('+7 days', $date)</literal> and not
      <literal>$date += 7*24*60*60</literal>)
      and leap years into consideration when working
      with these functions.
