Kentucky: where time stands still

We've been driving so much that time has stood still. Somewhere in the middle of a country road in Kentucky, both our phones started fluctuating by the hour on the time. 5:30 then 4:30 thenback and forth. Alien invasion? Nexus of the universe? Then a tiny sign appeared later on that declared our arrival in central time. Apparently, the border runs right through the state. Those poor cows separated in time from one another on the same farm. There's a bad moo related pun here somewhere, but I'm drawing a blank.
