Code to handle the PPS from the atomic clock, RTC and multiple time display for the Atomic Clock Revisited.
Mea maxima culpa is that I have an awfully messy 15 years old repo https://github.com/AlanFromJapan/alanarduinotools. It's the kind of thing you know it's bad, but would take so much time and energy to fix you leave as is. There's tens of projects there, barely none worth a dedicated repo.
I wanted to branch the MultiClockManager but it'd mean branching the whole repo. So let's make things clean for this present one project, big enough to have its own repo.
