can someone explain HOS reset to me?

That used to be printed on Crete's log book, I'm not sure if it was ever true or not.

 

HOS rules do not assume starting time of 0001, why bring a 24 hour clock into the discussion? 24 hour clock denotes a day of the week, i.e., 0001-2400 ... your 14 hour clock begins the minute you begin after a qualifying 10 hour break. Your drive/work time might carry through midnight, but that doesn't change hours available or hours driven/worked, just denotes how many hours consumed on that given day of the week.

 

If you are recapping hours, those hours come back at midnight of your home terminal time zone.
