Just as an aside, in a related thread user gfvalvo provided some test code and I have confirmed that the ESP32 time functions DO account for DST, even without NTP updates as shown below. After synching with NTP, I manually set the time for 11/2/25 01:59 which is a minute before DST ends in my time zone - and the ESP32 clock dutifully transition from 01:59:59 to 01:00:00 as it should.
Good to know and saves a lot of DST logic coding 
EDIT - I wonder if setting a boolean flag tracking if DST transitions have occurred would help towards preventing missed or duplicated hourly events at that hour.
