time keeping on mars

The red planet or Mars is similar to Earth. Even one Day of Mars and one day in earth is pretty much similar. The length of one martian solar day often called a sol is 24 hours 39 minutes and 35.244147 seconds, whereas a solar day in earth takes 24 hours and 0.002 seconds. Therefore a martian day is 2.7% longer than that of the earth.

Generally the rovers do their work in the day as they are operated by solar panels and cameras are used to do the work. The working schedule of the people who work on these rovers changes everyday by 40 minutes. So many of them keep two watches, one set at the timing of earth and one set at the timing of mars.
