One has to assume that this 'menomic memory circuit' Spock is talking about would be like a flash card reader today. Either that it is just his version of a joke.....
There never is any exact amount of time given as far as how long before McCoy arrives that K&S get there, but considering Spock has time to build his extracting circuit, watch it burn, and then rebuild it, one HAS to assume they were there a month at least. This would lend credence to the idea that Kirk has time to really fall for Edith. And Edith actually WOULD be a perfect woman for Kirk: intelligent....imaginative...strong moral base...a leader...in fact, in many ways, a female James T Kirk.
Another interesting thing is that somehow the tricorder somehow picked up fragments of BOTH time streams - another quirk of the Guardian? Or perhaps when McCoy broke the 'current' time line, both times lines existed for that nanosecond. Another thing to quibble about!
