    C++ user with operator overloading: “T2 minus T1.”

    Let someone else implement the class. There’s probably a library for it.

      Is there a straightforward way to know which overloading will be used or is it just a roulette every time you add a sketchy new library to your build?

      That’s fine if T1 and T2 include a datetime with the exact local timezone. A simple timestamp or timestamp + utc offset won’t work.
