FWIW I've found this source from Associated Press Of Pakistan http://www.app.com.pk/en_/index.php?option=com_content&task=view&id=39993 that states: "...clocks would be brought back to the actual time on September 1. According to DST, the sunrise in Islamabad will be at 6 a.m. instead of 5 a.m. and sunset at 8 p.m." Hope this helps. Regards, Alex
