DateTime fields can be textually represented by Time Difference View Editor in reference to the actual DateTime. It is much more understandable for the user to present the date/time information in this way in some cases. You can choose to present the datetime as the difference span from the current moment by using Time Difference Editor.
For example; it is possible to represent time with its relation with the current time as " .... days before", "...hours ... minutes after"
