With the Yesterday saga can an exact date be found for the back in time parts of this episode? -- 8of5 14:26, 8 January 2007 (UTC)
How about circa. 2699 B.C.? This is based on Geoff Trowbridge's dating of circa. 2700 for Yesterday's Son. [User: Stripey].
Well the pocket timeline puts Yesterday's son at 2703BC and Time for Yesterday at 2683 BC. Unfortunately I haven’t seen this episode or read either of the novels so my understanding is based entirely on what I can read here. Having another look I think the Zarabeth article might have helped, it states she died 17 years after Spock arrived originally and Spock returned 3 years after that, which would make this episode 20 years prior to Yesterday's Son so in 2723bc? -- 8of5 17:17, 8 January 2007 (UTC)
