In this new Trek timeline, it is 2258 or 59 or something like that. So '300 years' ago would be the 1950s. Have they retconned the dates of the Eugenics Wars again? Might have been better if they just merged WW3 and the Eugenics Wars into the one conflict, and said 200 years (the 2050s)
Its accurate because Khan would have born in the 1950's and was around 40 years old during the eugenics wars.
Wouldn't that make Khan around 300 years old in 2258?
