Hi.
It's high time we left if we really want to be on time.
It's from test No. incompl/inter-56 "High and Low", question 3.
Could you tell me why there is: It's high time we left; and not: It's high time we leave? Why is there Simple past tense used?
Thanx in advance.

Hi pivosz

"It's (high) time we left/went/etc." is a very standard expression and I'd say this form of the verb (left/went/etc.) is an example of the subjunctive. It basically means "we should go" / "we should leave"/ etc.

It only looks like the past tense, but it actually refers to the future.

It's similar to what you see in some "IF-sentences":
"If we left at 5 a.m. tomorrow morning, we would miss most of the rush hour traffic." The word "left" in this sentence also refers to the future.

Hi pivosz,

Just to add to what Amy has said, let me refer you to some material on the subjunctive that I've written for the site: Subjunctive
