I feel this comment betrays a misunderstanding of what language even is. Saying it like "two forty-five" or whatever is a figure of speech as much as "quarter to three" is.
No, I meant it. "Two forty-five" is a figure of speech. If you were giving the time in exact terms you'd say something like "it's been two hours and forty-five minutes since midday/midnight". You're just stuck in this idea that your way of expressing it is the right one.
That's the most arrogant reply you could've written. And I've just clicked on your name and seen your other comments, and it all makes sense. Wind your neck in and go outside.
