Hi, According to the episode, Trelaine only knew of the Earth of 900 years before. Since it took 900 light years for images to travel to Trelaine's rock and he was re-enacting Napoleanic Europe, where the writers implying that Star Trek occured in the 27th Century?
P.S... I accept that TOS occured in the 2260's.
