local mean time

1. Solar time as measured by the position of the mean sun with respect to an observer's local meridian. Like apparent time, local mean time differs continuously with the observer's longitude and is not standardized over a time zone. However, a day as measured by local mean time does not vary in length throughout the year—it is always 24 hours.
