-====== Real-time Martian Clock ======
-I had a momentary lapse last night - or was it inspiration? Anyway, I've added a real-time clock that shows the current time on Mars using the Martian clock (the seconds are a bit longer) for the location of the InSight lander.
-The lander is situated in the south-west corner of Elysium Planitia, and very handily, it's on a nice longitude. You can view the clock [[blog:aardvaark:mars_weather#current_time_in_elysium|on this page]]. [edit: there are now 3 clocks, one each for the prime meridian, InSight's location and mission time]
-=== ===
-Although the Martian day (a sol) is 24hrs 39mins 53secs, clocks on Mars are adjusted to a 24hr day. To make this happen, Martian seconds are longer by about 0.0275 secs. This is done purely out of convenience.
-Writing the clock was an interesting exercise. I had to calculate the current Martian year, month and sol, so I put those on the clock as well. If you compare the clock with other online calculators and see differences, remember they are probably calculating the time at the prime meridian.
-Below the clock in the [[blog:aardvaark:mars_weather#current_location_of_mars|Current Location of Mars]] section, you'll see the current season has been calculated too. The start and end dates of the season are approximated, but they'll act as a rough guide.
