Or use Wonder... I believe the class you're looking is called ERCStampedObject (or something like
that). Extend that instead of EOGenericRecord and you'll get created & lastModified for free.

It's not a good idea to use awakeFromInsertion because it's called everytime you insert an object into an editingContext.
I suggest you to use validateForSave and validateForInsert:


public void validateForInsert() throws NSValidation.ValidationException {
setCreationDate(new NSTimestamp());


    super. validateForInsert();
}

public void validateForSave() throws NSValidation.ValidationException {
setModificationDate(new NSTimestamp());


    super. validateForSave();
}

Hi there,

I need to add tracking fields to my database that
track when a record was last updated and when a record
was added.  I believe I can use the awakeFromInsertion
method on EOCustomObject (in the superclass for all my
EOs) to set the time the record was added but I'm a
little confused how I set the date last modified time
automatically?  Or, is this something I need to set on
the EO before I save changes?  Thanks...
