Fmt seems to have a formatter for std::chrono::time_point templated by
std::chrono::system_clock and (optionally) std::chrono::utc_clock if my
interpretation of the fmt/chrono.h code in the https://github.com/fmtlib
master branch is correct.
Quoting from https://en.cppreference.com/w/cpp/chrono/hi
Odd. How would we format the timestamp in that case? According to
the documentation, fmt has formatters for std::chrono::time_point
already.
Is this some sort of difference between MSVC and gcc? It should be
trying to format
std::chrono::time_point, which I
thought was std::chrono::system_clock
