Creating an ics file and time off by 4 hours

Here is my code and even though I set my timezone (eastern standard time and eastern daylight time) the calendar event is off by 4 hours – so i want the event to start at 9 am and end at 5 pm and I had to set it 4 hours ahead

[CODE]
echo “DTSTART:{$date}T130000Zn”;
echo “DTEND:{$date}T210000Zn”;
[/CODE]
