I'm sure the intent at the time was that warp drive had been invented recently.
I'm not so sure. If so, how did the
Columbia get to Talos? There's no attempt to imply that the ship would have been generational, or equipped with stasis or other classic scifi trickery. Vina was listed as a crew member in Number One's records - such records couldn't exist if Vina were of the n'th generation on a space ark. And the fake survivors don't give any indication of having been away from Earth longer than the 18 castaway years. Joe Tyler tells them they will get "back" to Earth, not that they will see it for the first time in their lives...
There would seem to have been an improvement in speed, but the
Columbia would supposedly have had a faster-than-light drive already.
Now, putting this all in the Trek context is another issue, and an oft-tackled and enjoyable one. We can speculate to our hearts' content, as we don't have to pay any heed to the intent of the writers there. The nature of TOS as an episodic series taking place in one and the same continuity already requires us to ignore writer intent for any given episode so that it fits the greater whole.
So essentially, we can invent meanings related to the word "time" that aren't just variations of the theme "time barrier is the dramatic analogy of the sound barrier". Anything goes. Perhaps the "barrier" is an engineering problem named after some scientist or engineer or test pilot called Tyme, now cleverly solved or circumvented? Perhaps it's a physical barrier that used to block the route between Talos and Earth, and while the
Columbia had to go around it, the
Enterprise is strong enough to push through with impunity?
No other aspect of Star Trek requires us to believe that ships got significantly faster between the crash of the
Columbia and the events of "The Cage". Indeed, ENT would postulate top speeds in the range of warp 6-7 around 2160, while TOS suggests that warp 8 was new territory in the 2260s - hardly a major leap.

P.S. What is it with basic politeness this past weekend? Not only is
3DMaster doing his usual thing -
Beaker also sounded downright rude here, which really isn't the norm. Can't we just get along, people?
