Mars24 Sunclock — Time on Mars
The Mars24 software displays a Mars sunclock, a graphical representation of the planet Mars showing its current sun- and nightsides, along with a numerical readout of the "standard" Mars time as well lander and other local times. Other displays include a plot showing the relative orbital positions of Mars and Earth and a diagram showing the solar angle and path for a given location on Mars.
Mars24 is a cross-platform application that runs on Macintosh, Windows, Linux and other desktop computers.
Mars24 requires a computer with a Java 9 (or later version) runtime environment installed.
