Dear Admiral Don Iago: No need for ad hominem attacks, is there? I have been visiting for years, and hope to make admiral myself someday, but simply had never come across star date analysts of this level of dedication before.
However, I find this sort of thing quite amusing to witness, whether years or star dates are the focus of interest. Somewhere out there, I'm sure, is a fan who has tried to show that "15 years" couldn't possibly mean the same thing to Khan and to Kirk unless either (i) Khan and his gang cared about Earth-timekeeping and/or were given appropriate timepieces when they left the Enterprise, or (ii) Ceti Alpha V had a year the same length as Earth's (on average, perhaps, considering that the planet's orbit had shifted!).
