Project: 
Introduced in branch: 
8.x
Introduced in version: 
8.0
Description: 

Files used to have a 'timestamp' column but the meaning of that was ambiguous. It was documented as the file creation time but used to track file change time with no file (entity) creation time tracking in the database. In Drupal 8, we now have a standard 'created' timestamp for the creation time and a 'changed' timestamp for tracking changes.
