C++ How do I convert a std::chrono::time_point to long and back

Question

I need to convert std::chrono::time_point to and from a long type (integer 64 bits). I´m starting working with std::chrono ...

Answer 1

time_point objects only support arithmetic with other time_point or duration objects.

You'll need to convert your long to a duration of specified units, then your code should work correctly.
