I read elsewhere that it was every 12.4 hours. This leads me to wonder if there's any connection between that and us having a 25 hour clock which has to be corrected every day by the light of dawn instead of a 24 hour clock which doesn't need correcting to such a huge degree.

Hi David

you're right - it is 12.4 hours - I simplified it to 12, because perhaps unfairly, I assumed that most people wouldn't be interested in this particular detail. But the reason it's 12.4h, I believe, is because tides move on about 1 hour each day; so adopting this rhythm correctly anticipates the later time of the next tide.
