Planet: Mirage. The division of the sixty marbec rotation of the planet Mirage into a thirty marbec period of light, or Alpha Time (A), and a thirty marbec period of darkness, or Omega Time. In the popular vernacular, Omega Time is referred to as “moovunit” and Alpha Time as “dontmoovunit”, relating (obviously) to travel on the planetary surface, which nobody does anyway, so the reference is moot. The term “malton unit” is not used for either the Alpha or the Omega unit, because of the time disparity.
