Date/time is always stored as UTC in GPX files, so unless you actually changed the date and time in your camera to local time while in Istanbul, you shouldn't need to apply any shift that you wouldn't normally apply within your own time zone. You would only need to shift the time by whatever amount you changed your camera's clock during the trip, if that helps... all of which assumes you normally keep your camera clock set to local time, of course.
