Present and past subjunctive
The terms present subjunctive
and past subjunctive
can be misleading, as they describe forms
rather than meanings
: the past and present subjunctives are so called because they resemble the past and present indicatives, respectively, but the difference between them is a difference in modality, not a temporal one.

Ex: It's high time (that) the children were in bed.
Ex: It's about time (that) the children were in bed.
