Mars sky at sunset, as imaged by the Spirit rover (May, 2005). Mars sky at sunset , as imaged by the Curiosity rover (February 2013; Sun simulated by artist).

As Mars2020 touched down mid afternoon local time, a clock started at the time of touchdown would lag between the mission clock by about 15 Mars hours." [use SpaceCraft Event Time (SCET) rather than Earth Received Time (ERT) which may be "off by about 14 minutes"].
