Saltah'na clock

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 and displayed it on his desk on Deep Space 9. 

The Saltah'na clock was not simply an ornament to Sisko as he used it to tell the time on occasions.
