In short? No.
In long? The guy is mad as a hatter. And still wrong. The problem with his theories are numerous, but the basic problem is that he assumes time is somehow divinely linked to the rotation of the earth around the sun. His theory boils down to the fact that, since when it is noon at your house, it is dawn at someones, dusk at someone elses, and midnight at someone elses, there are four seperate days. Even by his own logic he is wrong, there should be, variably, either 24 days (One per time zone), or an infinate number of days, as each miniscule rotation around the 360o of revolution of the earth produces another day.
But the problem is his 'theory' doesn't account for the fact that time is in no way linked to our sun, our earth, or even us. Time is just a thing. We mesure it, sure. And we use the rotation of our planet around the sun as a handy reference. But it's not connected in any way. An astronaut floating in space still has "time". The sun itself still has "time".
