We have a few fields on a custom object where field history is tracked.  However, those fields are updated with an Apex trigger.  It does not appear that the fields are tracked when the field is updated with the Apex Trigger.  Is this accurate?  The records could have been created before the fields were tracked, so I can't confirm based on the data alone if the field tracking is respected or not.  Thank you!
