In turkle time a lin is the briefest moment that can just about be measured. Ninety lins make a tikk, one hundred tikks make a lod, thirty eight lods make a yan, the time it takes the planet Ankor to make one complete turn in the path of the star, Ruru, its main source of light and warmth. Ten yans make a zac. Six zacs make a yod, twenty yods make a zik. Twelve ziks make a zan. Sixteen zans make a nik.
