The absence of Captain Kirk from the Enterprise for an entire year, and Spock's temporary promotion and uniform change make this story difficult to reconcile with the timeline later established in canon. One possibility is that the use of the Guardian of Forever caused the reversion of these events from the characters' history, even though they might still carry memories of these events.
