I understand your position.

One of the things I’ve been considering in relation to the Defiant’s database is whether we should consider the dates in there artifacts or translations.

When I was younger, I thought the reason for the existence of stardates was to account for relativistic effects when ships were travelling at sublight. Not exactly what they are supposed to be but the point is that Starfleet is aware that relativistic effects occur and adjusts for them in recording times and dates.

An artifact date in the Defiant’s historical database would be a record that has a fixed date that wouldn’t be adjusted by the computer or the universal translator. I think that’s what most of us assume it would have been when we see the graphics onscreen.

However, there’s a possibility that it was something else, a date that may have been translated or adjusted for some reason, either in relation to the war or in relation to the Defiant’s own continuity. That’s to say the ship may in itself not be a reliable narrator in its own continuity.

I agree however that we shouldn’t assume a shift in specific dates until and unless we get it onscreen - just that we should equally avoid going so far as to break the sequence of causality in order to respect a given date.
