C++ and C# are different languages. They have different rules for handling type promotion in the event of comparisons. In C++ and C, they’re usually compared as if they were both unsigned. This is called “unsigned preserving”. C++ and C compilers traditionally use “unsigned preserving” and the use of this is specified in the C++ … Read more
uint isn’t a standard type – unsigned int is.
C++20 introduced a guarantee that time_since_epoch is relative to the UNIX epoch, and cppreference.com gives an example that I’ve distilled to the relevant code, and changed to units of seconds rather than hours: #include <iostream> #include <chrono> int main() { const auto p1 = std::chrono::system_clock::now(); std::cout << “seconds since epoch: ” << std::chrono::duration_cast<std::chrono::seconds>( p1.time_since_epoch()).count() << … Read more
Unsigned int isn’t CLS compliant and would therefore restrict usage of the property to those languages that do implement a UInt. See here: Framework 1.1 Introduction to the .NET Framework Class Library Framework 2.0 .NET Framework Class Library Overview
