...As opposed to a TOS source with erroneous retconning?
Whatever little continuity TOS ever had, all of it was of the "ret" type - writers thinking they remember an interesting tidbit from an earlier episode, but completely misremembering it (General Order 7 involves death penalty - or was it General Order 4?) or choosing to twist it till it's unrecognizable (one of Spock's ancestors once married a human - Spock's dad lives with Spock's human mother). Most often, there just wasn't any effort (TOS takes place 200 years in the future, except when it's 900 years, save for when it's 300 years or more than 1000 years). That in mind, the Voyager references (this "11:59" one included) were almost too reverential to the crappy "original" material...
Whatever. Lets just say it's easy to see why I ignore a lot of what came later as getting it wrong rather than going on about how TOS was wrong.
