About Solar Time
Local Apparent Solar Time (LAST) is the time shown by a sundial. It differs from clock time due to: (1) the Equation of Time - caused by Earth's elliptical orbit and axial tilt, and (2) longitude difference from the timezone's standard meridian. Mean Solar Time averages out the Equation of Time variations throughout the year.
