Adverb Clauses of Time
While adverb clauses generally answer the questions when, where, why, and how, adverb clauses of time give more details to answer the question when. An adverb clause of time must start with a subordinating conjunction, such as before, after, when, while, until, since, by the time, as soon as, and others.
If the adverb clause of time comes before the independent clause, place a comma after it to show that it is introductory material. If the adverb clause of time comes after the independent clause, no comma is needed.
