What is the point of using the past simple with "high time"
I have a couple of books that discuss the
origin of the past form in the subordinate clause of the "It is time [that] . . ." construction, to which the "It is high time [that] . . ." construction is obviously closely related. The independent clause of such constructions is "It is (high) time." In earlier English (Old, Middle, and Early Modern), the "be" verb in the independent clause was often the past subjunctive form "were." For example, in the novel
Ivanhoe (1820), by Sir Walter Scott, there is the following sentence:
"
It were time we left our wine flagons."
According to Francis James, in his work
Semantics of the English Subjunctive (UBC Press, 1986), "[t]he past subjunctive has no current uses in independent clauses" (p. 70); however, "it survives in conditional clauses and object clauses, both of which are dependent" (p. 73). He gives a couple of paraphrases with conditionals, the implicit idea being (as I understand it) that the "It is time [that] . . ." construction makes a use of the subjunctive (or modal forms) comparable to what we find in the subordinate clause of Type 2 conditionals (viz., "If we
left our wine flagons, it
would be [formerly
were] good").
Francis James gives the following paraphrase for "It
were time we
left our wine flagons": "'If we left (were to leave) our wine flagons, it were (would be) time' (i.e., it would be a good time or the right time)" (p. 77). As for "It
is time we
left our wine flagons," he states that it "is roughly comparable to the sentence, 'It would be desirable if (one would wish that) we left our wine flagons, because it is high time to do so,' and represents the state of affairs, 'our leaving our wine flagons,' as an imagined possibility" (p. 83).
