Azan and solat 24/7

I received an email today 'AZAN: THE AMAZING PHENOMENON'.
The email is long, but in summary it says that due to difference in the local time, the phenomenon where azan is heard around the world at every single moment, occurs.

The azan is a phenomenon. In fact, Allah's decree on the whole universe is a phenomenon.

Our prayer times are determined by the position of the sun. Therefore azan is heard at EVERY single second due to the earth's rotation, and at any single moment, it is subuh for some people, zohor for some, asar for some, maghrib for some and isya' for some. And I imagine, if we can hear the call to prayer from all over the world, the azan would have sounded like an indefinite continuous wave. Subhanallah.

And not only can the azan be heard at every moment, as-solat is being performed by somebody around the world at any point in time. At any minute you're reading this, somebody on this earth is performing their ruku' and their sujud.

Lord of the two Easts, and Lord of the two Wests;
Which is it, of the favors of your Lord, do ye deny?
