The pattern that seems to have been true for Kapiolani - where Obama now says he was born (as opposed to the earlier claim that it was at Queens) - is that the BC’s were collected for a week and then on Friday the doctors signed the certificates, the (deputized) local registrar at the hospital signed the certificates, and then all that week’s certificates were transmitted to the state DOH office - as required to be done weekly by Section 8 of “Public Health Regulations”, Chapter 8. The certificates were signed, delivered, and numbered on Fridays, for Kapiolani.
Doing it weekly makes sense since the requirement was that births be reported within 7 days. It would have made an orderly process.
Let’s suppose that there was an authorized registrar at the hospital. She likely would have been a head nurse or someone like that. It’s likely that she would have been the one to stamp the date filed because it seems to coinside with the date the doctor signed the certificate. Her signature wouldn’t be enough even in 1961. She would have needed to reflect a date somewhere.
Then let’s suppose that her weekly stack of certificates are sent to the state for verification and certificate number assignment. The clerk at the state registrar’s office receives a pile of paperwork with the 8th on the bottom and the 11th on the top because that’s how the hospital stacked it in their outgoing tray. The clerk approves and stamps the certificate number on each paper working from the top down in the stack.
Do you see what I’m getting at? There are multiple plausible explanations for why those dates and numbers don’t match up in your mind. That’s not to say that your theory is totally wrong or disproven. I just want you to consider that there could be other explanations before you jump off the bridge screaming that you’ve proven the COLB a forgery.
Would it matter that 0bama's time of birth was about 7:30 PM, which would make it after a weekly transmission done during normal adminstrative hours?
