What is a time clause and how is it used to indicate time?

A time clause is a type of dependent clause that is used to indicate when an action or event takes place in relation to another action or event. It typically begins with words such as "when," "while," "after," "before," "as soon as," "until," or "since." The time clause is used to provide additional information about the timing of the main clause in a sentence. For example, in the sentence "I will go to bed when I finish my homework," the time clause "when I finish my homework" indicates the specific time when the action of going to bed will occur.
