Are There 'Starfleet Regulations' that ''Order'' the Captain to Keep a 'Ship's Log'?

I wondered this morning, 'Does Starfleet (what they call The United Federation's spaceship fleet) have regulations that command captains to keep a ship's log? to record an entry every day? 'I bet there'd be a lot of "nothing"-entries---"Captain's Log, Stardate (#####-point-#): another couple-dozen light-years today ... still---nothing. That is all." I 'Bing'-ed "Are Captain's Logs required by starfleet regulations" (and a few other similar search), and looked through a few of the lists of 'starfleet regulations'; but I found nothing about the captain keeping a journal ... not even a page that specifically outlined the role of 'starship captain!' So 'did' ('does'? 'will'?) Starfleet require captains to keep a log? Hey (conspiracy theory here), maybe 'the captain's journals' were the only evidence we have that Starfleet 'ever will have existed' (some weird paradox where they went back in time, an accident forced them to lose some of the ship's records in the ocean, Gene Roddenberry happened upon them while he was cleaning the brig or something, and he invented Starfleet after getting the files decoded and translated!
