Instead, you will see an approximate value that is divided into four sections. Last seen recently covers 1 second to 2 or 3 days. Last seen within a week covers a period from 2 or 3 days to 7 days. Last seen within a month covers from 7 days to one month. Finally, Last seen a long time ago will be displayed for those users who have not connected for more than a month.
