Deprecated migrate to @WhenCreated.
For a timestamp property that is set to the datetime when the entity is
created/inserted.


This is effectively an alias for @WhenCreated which was added as it hints
towards a better naming convention (WhenCreated, WhenModified).




An alternative to using this annotation would be to use insertable=false,
updateable=false with @Column and have the DB insert the current time
(default value on the DB column is SYSTIME etc).




The downside to this approach is that the inserted entity does not have the
timestamp value after the insert has occurred. You need to fetch the entity
back to get the inserted timestamp if you want to used it.





Example:



  @CreatedTimestamp
  Timestamp whenCreated;
