> Key: MINIFICPP-1636

> C++17 support allows us to use std::filesystem instead of the currently
> equivalent boost library calls. We should also investigate where
> std::filesystem could be used instead of a platform specific implementations.
> Note: std::filesystem::last_write_time returns
> std::filesystem::file_time_type which uses a platform dependent clock. This
> makes it hard to replace the previous implementation as the time since epoch
> can be different in two systems, the conversion to time_t can be difficult
> and also out usage of time strings may be problematic. Cpp20 standardizes the
> std::filesystem::file_time_type with std::chrono::file_clock which solves
> these problems, so it may be better to implement this when we have full Cpp20
> support.
