Get current time in milliseconds, or HH:MM:SS:MMM format

Question

I\'ve written a c++ function to get the current time in HH:MM:SS format. How can I add milliseconds or nanoseconds, so I can have a format like HH:MM:SS:M

Answer 1

This is a cleaner solution using HowardHinnant's date library.

std::string get_time()
{
    using namespace std::chrono;
    auto now = time_point_cast(system_clock::now());
    return date::format("%T", now);
}
