In this age of smartphones and digital wrist watches, the Barnwell Sundial in front of the Court House in Barnwell, South Carolina continues to tell accurate time. As reported by the television stations WRDW and WAGT,  "It was put up in 1858 after it was given to the county by state senator Joseph D. Allen. The sundial keeps very accurate standard time, even though that wasn't established until 1884. [Telling standard time is possible through Equation of Time corrections listed on the face of the dial.]  The courthouse that is located near it burnt down in 1865, but the sundial stood tall.  In 1918, still in it's original location, a concrete curbing was built around the sundial to protect it from traffic. Over the years, it was restored and fixed up."

See the video of Phill Huggins tell about how he got the opportunity to restore the sundial.
