Sử dụng thì hiện tại hoàn thành, chúng ta có thể xác định một khoảng thời gian trước hiện tại bằng cách xem xét thời gian đó, với for + một khoảng thời gian, hoặc xem xét lúc bắt đầu, với since + một khoảng thời gian. FOR và SINCE cũng có thể cùng được dùng với thì hiện tại hoàn thành. SINCE chỉ có thể dùng với thì hoàn thành. FOR có thể dùng với thì quá khứ đơn giản.
