Consider these possibilities:
- It is now time for her to leave home.
It is now time for her to be told. - It is now time (that) she left home.
It is now time (that) she were told. - It is now time (that) she ?leaves home.
It is now time (that) she ?is told. - It is now time (that) she ?leave home.
It is now time (that) she ?be told. - It is now time (that) she ?must leave home.
It is now time (that) she ?must be told.
Why is (2) the correct way to express (1)? Why does the infinitive used in (1) shift to past tense, not to present tense?
Are any of (3), (4), and (5) grammatical? If so, are they equivalent to (2)?
Probably it has to do with the “missing” subjunctive in English, but why is the past tense used here instead of the present tense?
What do you English native speakers have to say about this point?
