In general, one gets surprisingly consistent results if one treats the four-digit stardates of TOS as merely truncated five-digit or six-digit ones. The difference would be the same as between "the sixties" and "the nineteen-sixties"...

Could 38774 fall on 2264, in terms of this interpretation? Well, the "22" part would depend on the dropped first and second digits in a putative seven-digit date, so no problem there. The "sixties" part would depend on the 3. Not a good match for the twenty-four-sixties, where this digit is 4 for years 2264 through 2273. (Or perhaps 2263 through 2272, depending on the month when stardates roll over.)

The "year four within the decade" part would in turn depend on the 8. In TNG, year four is directly associated with the stardate 41986 in the episode "The Neutral Zone"...

So... SD 38774 could plausibly be for example the TOS year 2251, but not 2264, not per this system.

Then again, the stardate comes from "Unimatrix Zero" where Tuvok is slowly being assimilated and going crazy - whereas the birth year 2264 comes from "Flashback" where Tuvok insists he was 29 years old in 2293, during events he is grossly misremembering anyway, due to an alien entity messing with his brain. Not too difficult to dispute either number, or both.
