Hi
i am implementing review and comments functionality. In this Feature ,once user comments on any review then new user should be able to see the time difference between present time and the time when the comment is posted.

ex. 20 minutes ago

4 hours ago

1 day ago

Please share the solution if anyone has as soon as possible

Thanks in Advance
