/*
* MARS TIME face
*
* This watch face is dedicated to Martian timekeeping.
* It has several modes, and can display either a time or a date.
*
* Pressing the ALARM button cycles through different time zones on Mars:
* MC - Mars Coordinated Time, the time at Airy-0 Crater on the Martian prime meridian
* ZH - Local mean solar time for the Zhurong rover
* PE - LMST for the Perseverance rover
* IN - LMST for the Insight lander
* CU - LMST for the Curiosity rover
*
* Press the LIGHT button to toggle between displaying time and date:
* MC S - the Mars Sol Date, Martian days since December 29, 1873
* ZH Sol - Mission sol for the Zhurong rover
* PE Sol - Mission sol for the Perseverance rover
* IN S - Mission sol for the InSight lander
* CU S - Mission sol for the Curiosity rover
*
* Note that where the mission sol is below 1000, this watch face displays
* the word “Sol” on the bottom line. When the mission sol is over 1000, the
* word “Sol” will not fit and so it displays a stylized letter S at the top
* right.
