Verb-tense agreement for a quote that is still true
Sequence of tenses requires us to use, for example, past tense if the verb in the introductory clause is in the past tense. For example:
All the members of the survey team said: “You have a beautiful library!”
All the members of the survey team happily acknowledged that we had a beautiful library.
This holds true if the quote is a universal truth, quite obviously. But, what if the physical situation talked about in the quotation still holds true? For Example:
Sarah: Yes this is she.
Sarah: Oh really!
Sarah: Well, your ring awoke us.
Sarah: No, I have no laundry outside.
Sarah: Thanks, Bye!
Jeff: Who was it?
Sarah: it was Betty.
Jeff: What did she say?
Sarah: She said that it was raining / it is raining. (Now, here the logical sequence does not follow the grammatical sequence,)
The survey team said about Plymouth High School, “They have a beautiful library.” (in March 2012)
Subsequently talking to the principal of Plymouth school, Saba told her that the committee commented that (you had a beautiful library / you have a beautiful library). (May 2012, and the situation still holds true).
