The clock is composed of a sphere, held at an angle in a semi-meridian mounting and raised on a pillar or stanchion like a globe. Around the globe's equator is marked with the D'ni numerals from zero to twenty-four, representing the 25 "bells", or partahvotee, of the D'ni day, with a dot midway between each numeral. The zero bell is represented by the "wrapped zero" ( = ) A downward-facing magnifying lens is affixed to the pillar as well, allowing observers to see the current partahvo as marked out on the globe, and the globe rotates clockwise as viewed from the front.
Before the fall of D'ni, the bells were marked by actual chimes. However, if the gorahyantee were the source, the mechanism is no longer functional.
The gorahyantee in the D'ni neighborhoods keeps proper 30-hour days, but the clocks are presently approximately 11 hours and 36 minutes off of actual Cavern Time based on explorers' observations in September of 2018.
The gorahyan in Relto is broken, and does not keep time.
It is unclear whether the term "gorahyan" only applies to these clocks, or if it can be applied to other timekeeping devices such as Aitrus's watch, Gehn's watch, or the tahvo timer in the Ahnonay workshop.
