Do you have the time?

How many clock towers does Chennai have? The question popped up when I was travelling past the Royapettah clock tower a couple of days ago. I had my camera with me, so I just had to take this picture, but the question remains. How many clock towers?

I can think of others at Vepery, Mint, Triplicane (and there was one in Tambaram that was brought down to make space for the National Highway) - apart from the ones on buildings such as P.Orr or the Chennai Central station. I guess I'll try and run a (fragmented) series of the clock towers :)

I'm sure there is some history behind the building of these clock towers; yes, the utilitarian value of telling time must have been the primary purpose, but who decided that the populace of the city needs to keep track of time? Will also pick up some information and link to this post - later!
