When the action as well as the time is considered unfinished, the verb loads up on third form helping verbs ("to be" and "to have") and changes to the progressive form.
For example:
Western countries have been waging wars in the Middle East for thousands of years.
I have been drinking tea all day.
Mary's dog has been barking like crazy since it was born.
