Editable Dates and the authored_on Field
A defining trait of a blog is its chronological order. In the past this crucial date and time was stored in the created_on field whose default was the first time a post was saved to the database.
MT has permitted authors to change this time and date (timestamp) to enabled scheduling a post for future publication or post dating a post when migrated. When changed the created_on fields in the database would be changed. The problem is that the sometimes useful information of knowing when a post was entered into the database was lost.
MT4 introduced a third timestamp field that joins created_on and modified_on in entries and the newly added pages. Now when an author changes the date of a post or page it’s reflected in the authored_on field.
While this change is transparent to users, some older plugins that worked in MT3 will seem to ignore these changes and list entries in “the wrong order.” Many pre-MT4 plugins are sorting on, and even selecting by, the created_on field which will cannot be edited through the MT interface.
Just something to keep in the back of your mind going forward.
