This tutorial is designed to explain you how date and time stamp can be viewed in a comment.

When you post a comment within a record in Simply CRM, the comment only displays the time duration since the comment was posted. For instance, I had commented on a record last month;so, it displays 1 month ago

If you want to see the time and date when the comment was posted, simply hover your mouse pointer on the time duration text. From the above example, I will hover mouse pointer on I month ago to view actual details
