@user_not_found Standard Time 
September 30, 1951 was the standard time 
in Pakistan.
Pakistan’s standard time is taken from @Shakargarh
“Din Panah” is the place where the first rays of the sun fall on Pakistan. This village was located in the middle of Din Panah Bhaipur and Lalian. This village has completely disappeared. Now there is only one mosque left. This is where the border of India ends and the border of Kashmir and Pakistan begins.
Pakistan’s standard time is five hours ahead of Greenwich Mean Time. It was appointed by eminent mathematician Professor Mahmood Anwar. The Government of Pakistan announced its authorization on September 30, 1951 and it came into force on October 1, 1951.
Prof. Mahmood Anwar is the Pakistani who proved that Pakistan’s standard time is half an hour behind that of India. The Pakistani government accepted his suggestion and set Pakistan’s standard time to be half an hour behind India’s.
