Department of Temporal Investigations
A pair of agents from the Department of Temporal Investigations drop by to have a stern chat with Benjamin Sisko in iconic Deep Space Nine time-travel episode “Trials and Tribble-ations” (read a full retrospective here!), while temporal agents and temporal incursions have also appeared elsewhere. This is Star Trek, after all! Enterprise, for instance, featured a temporal agent named Daniels, played by Matt Winston—and Voyager once sent Seven of Nine on a time-skipping adventure involving the USS Relativity, staffed by members of the Temporal Integrity Commission.
