In C++ it would mean that std::chrono::utc_clock (the clock that portably includes leap seconds, https://en.cppreference.com/w/cpp/chrono/utc_clock) could now do constexpr computations (compute at compile-time).  This would be a good thing, making some things more efficient both in cpu time and code size.
