When you use it
Use this when a sentence joins two actions with when, before, after, as soon as, until or since, and you must choose the correct tense in the time clause.
Watch out
Do not put will inside a time clause that starts with when, before, after, as soon as or until. Write 'I will come as soon as I finish eating', not 'as soon as I will finish'.
