In ArcCatalog I'm looking at a feature's table fields.
The DATECREATED column is empty for all features.
How can one determine when a specific feature was created?

This would be very difficult to implement in shape file. I would have to assume that what you are looking at is not shape.
There are several ways to implement with differing levels of difficulty.
in a pgdb, fgdb, or rdbms. You can implement rules and make the field required. (you would need to establish a value for all existing rows). Anytime a new feature were created, or existing edited it would require a value to be input.
as mentioned by Kirk - you can use an extension to create "custom" objects that trigger the application to insert or request currdate.
If using an rdbms you could build an application in it to manage the triggers.
The way to do this nowadays is by Enabling and managing editor tracking:
Editor tracking allows you to make a log of who edited data and when they did it. Once tracking is enabled, each time an edit is made, information about editors is automatically recorded in the fields you specify.
