/*
 * 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.
