Present perfect continuous Tense:- The present perfect continuous is used to refer to an unspecified time between ‘before now’ and ‘now’. The speaker is thinking about something that started but perhaps did not finish in that period of time.
He/she is interested in the process as well as the result, and this process may still be going on, or may have just finished.
It is the least used form of present tense. Present perfect progressive is used to indicate an action that began in the past and is still occurring in the present.
