The Saltah'na clock was a clock used by the Saltah'na race. In 2369, Benjamin Sisko built a replica of a Saltah'na clock while he was under the control of Saltah'na energy spheres. Even after he was freed from the spheres' influence, Sisko kept the clock (although he retained no memory of actually building it) and routinely displayed it on his desk on Deep Space 9. (DS9 episode: "Dramatis Personae") The Saltah'na clock was not simply an ornament to Sisko as he actually used it to tell the time on occasions. (DS9 novel: Devil in the Sky)
