Chronometer

Memory Beta, the wiki for licensed Star Trek content.

A chronometer is a devise used to track the passage of time.

Starships use chronometers to keep records of time passing, this can often be useful when something happens to the crew of a ship that causes them to lose track of time. When the USS Enterprise was attacked by the Ngultor consulting the chronometer informed the crew they had been incapacitated for forty-nine minutes. (EV comic: Flesh of My Flesh)

Chronometers of Constitution class starships in the 23rd century featured a bridge readout which displayed the time as a stardate and on a shipboard twenty-four hour clock. (TOS episode: "The Naked Time")

Data had an internal chronometer. While experimenting with non-androids' experiences of passing time, William T. Riker advised Data to turn off his internal chronometer in order to make the simulation more real. (TNG episode: "Timescape")
