Biz past perfect continuous ni, present perfect continuous ni o’tgan zamon shakli sifatida ishlatamiz. Bu degani, past perfect continuous o’tgan zamonda boshlanib o’tgan zamonda tugagan ish-harakatlarni davomiyligiga urg’u beradi. Present perfect continuous esa ish-harakatni davomiyligiga urg’u beradi, ya’ni o’tgan zamonda boshlanib to hozirgi zamongacha davom etayotgan ish-harakatlarni ifodalaydi.
