title: ical with php without needing to put timezone
body: <p>I have created ical file from php and it works fine. but when I import into the google calendar, it changes the time. </p>
  
  <p>after doing research, it's timezone issue. so I tried fixing it by removing Z (UTC) from the time, but time is still wrong after import.</p>
  
  <p>is there a way that if I set following event time, it should work fine for all the import, regardless on which timezone they have set for there calendar.</p>
  
  <pre><code>        $ical ="BEGIN:VCALENDAR\n".
                  "VERSION:2.0\n".
                  "PRODID:-//hacksw/handcal//NONSGML v1.0//EN\n";
  
          $start  = strtotime('2013-7-26 2:36 am');
          $end    = (60*1); // end in one minute
  
           $ical .="BEGIN:VEVENT\n".
