Earlier quoted context omitted.
"some" and "the" are not mutually exclusive. If I say there's some cake in the kitchen, that doesn't mean it's not the only cake in the kitchen.
Ok i see that you are being deliberately obtuse. Because by saying some, you meant time aspect was not primary. Which is wrong. Anyway, I have put a bit more information about this tense up in the discussion.
No I didn't and I was not being deliberately obtuse. That's not what "some" means here. Pretend I used no word instead of "some" — it would have had the same meaning. I get the impression from your grammar that you are not a native English speaker. That's fine, but then you may not have a complete grasp on something like this.
