Although TGM, like Primel, considers the mean solar day a “mundate reality”, its base unit of time, the Tim, is actually a simple power of the half day, or semi·day, rather than the whole day. In fact, it is equivalent to the semi·pentcia·day, or 10−5z half-days. In Primel terms, the Tim is equivalent to 6 ⚀timels, and the ⚀timel is equivalent to 2 uncia·Tim.
Although the TGM time units are not whole dozenal powers of the ⚀timel, each is a simple multiple of one, so we could incorporate them into Primel as auxiliary units:
