Yes, and I just want to know whether they depend on their context or, like Q6 and Q7, they have a fixed usage.

Let me explain why I'm asking you my questions all over again:
I suppose you native speakers think there ARE some ambiguities in Q1~Q5 because of the "exactly what time" problem, as Colin wrote.
However, I believe you don't think there is such ambiguity problems in Q6~Q7.
I just want to confirm whethere my assumption is right or wrong.
After this assumption is confirmed, I think we can develop our discussion further and reach a conclusion.

@Mari-LouA Sorry, but I think math is even harder than language, LOL! Good to see you around. =)
