+Some people's work schedules use Mars time.  Jet Propulsion Laboratory
+(JPL) coordinators have kept Mars time on and off at least since 1997
+for the Mars Pathfinder mission.  Some of their family members have
+also adapted to Mars time.  Dozens of special Mars watches were built
+for JPL workers who kept Mars time during the Mars Exploration
 Rovers mission (2004).  These timepieces look like normal Seikos and
 Citizens but use Mars seconds rather than terrestrial seconds.
