About this clock
Oak Ridge does not keep Tennessee's usual time
Most of Tennessee is on Central Standard Time, but Oak Ridge keeps Eastern Standard Time — 1 hour ahead of the rest of the state. This is the kind of thing that catches people out, and it is why the zone is resolved from the city’s own coordinates rather than assumed from the state.
Oak Ridge is currently on standard time. The next change is Sunday, March 14, 2027, when 2:00 am becomes 3:00 am local time.
Oak Ridge sits at 35.97°N, 84.29°W. For sunrise and sunset there — which do depend on exactly where it is, unlike the clock — see sunrise and sunset in Oak Ridge.
Clock time against sun time
The clock says the same thing everywhere in Eastern Standard Time, but the sun does not. Over Oak Ridge it is highest at 12:21 pm today — 21 minutes after clock noon.
At 84.3°W, Oak Ridge sits 37 minutes of solar time west of Eastern Standard Time’s 75° meridian, so on standard time the sun peaks 37 minutes after noon.
