How did you come to that conclusion? Googling for "Karachi PKDT"
produces no hits that would suggest PKDT to be a valid timezone name.
This (http://www.speaking-clock.com/Asia-Pakistan-Karachi_212.html) and

(http://www.timeanddate.com/worldclock/clockchange.html?n=757&year=2009)
also agree that PKT is the abbreviation for the winter time and PKST for
the summer time.
