Answer 3

It depends upon which series you are talking about. The series ranges from the 22nd century through the 24th. During Jonathan Archer's command of the experimental Enterprise NX-1 it was set a few generations after the first contact with the Vulcan in 2063 which would be around the 22nd century. About a century later James T. Kirk was in command of the Constitution Class Enterprise NCC 1701 and later the NCC 1701-A. That was around the 23rd century. Another 100 years later we meet Jean-Luc Picard in command of the Galaxy Class Enterprise NCC 1701-D and later the Sovereign Class Enterprise NCC 1701-E. Circa the Enterprise E era Benjamin Sisko was in command of the previously Cardassian run Deep Space Nine space station and Captain Janeway was in command of the Voyager which was lost in the Delta Quadrant deep in Borg territory. Some years later Romulus was destroyed and Spock and a renegade Romulan named Nero time-traveled back to the 23rd century creating an alternate timeline.
