Just in time for Ramadan the new clock tower built in Islam's holiest city - Mecca begun to tick.
The clock has four faces which are each 151ft in diameter.
The clock will run on Arabia Standard Time which is 3hrs ahead of GMT - but Islamic scholars hope the clocks influence will spread further than Saudi Arabia as the plan is for Mecca to eclipse the Greenwich Observatory as the true centre of the earth!!!!
The clock faces will be illuminated by 2 million LED lights along with a arabic script which reads "In the Name Of Allah"
When the spire is added and topped with the crescent which symbolises Islam it will stand 2000ft, which will make it the world's second tallest building.
Five times a day 21,000 green and white lights will flash to remind residents of Mecca when it is time to pray. These lights will be visible at a distance of 28kms.
The clocks four faces will each be covered with 98million pieces of glass mosaics.
