about time too

An expression used to emphasize that something should have occurred a long time ago. They're finally hiring some extra help around here, and it's about time too—another one of my employees resigned today. Tom finally moved out of his parents' house? Well, it’s about time too—he's 40 years old. Somebody finally confronted Sarah about her attitude, and it's about time too. Her snotty arrogance is intolerable!
