Comment 29 for bug 838525

It occurs to me that calling auditor.update_auditors() will simply truncate the DoB value as discussed above. For consistency, we should probably manually change the DoB type on auditor.actor_usr_history and apply the same "dob + '3 hours'" logic used on actor.usr. We should still call update_auditors(), because it does other stuff, but after the manual column change. I'll look at fixing that and force-pushing.
