Muslim scientists and clerics have called for the adoption of Mecca time to replace GMT, arguing that the Saudi city is the true centre of the Earth.
He said the English had imposed GMT on the rest of the world by force when Britain was a big colonial power, and it was about time that changed.
A prominent cleric, Sheikh Youssef al-Qaradawy, said modern science had at last provided evidence that Mecca was the true centre of the Earth; proof, he said, of the greatness of the Muslim "qibla" - the Arabic word for the direction Muslims turn to when they pray.
