TIME CLAUSES
Time Clauses are introduced with time conjunctions or expressions such as: after, as, as soon as, before, by, by the time, hardly... when, immediately, no sooner... than, now that, once, (ever) since, the minute (that), the moment (that), then, the sooner... the sooner, till/until, on/upon, when, whenever, while.
He waited for an hour before he was interviewed by the manager.
Time Clauses follow the rule of the sequence of tenses; that is, when the verb of the main clause is in a present or future tense, the verb in the subordinate clause must be in a present or future tense too, and when the verb of the main clause is in a past tense, the verb in the subordinate clause must be in a past tense too.
/' // watch TV after I have finished doing my homework. She left before he came.
We never use a future tense in a future time clause; instead, we use a present tense.
They will leave in an hour. I'll do the washing up then.
I'll do the washing up when/after they leave/have left, (not will leave or will have- loft)
Compare:
when (time conjunction) + present tense
When I find it, I'll tell you.
when (question word) + present tense + future
When will John get back from Austria?
