In Ada you can do something similar:
Or with package Ada.Real_Time:
Or use `delay until`:
`delay until` is useful in loops because `delay` sleeps at least the given duration, so you get drift. (You call Clock only once and store it in a variable before the loop and then update it adding the time span each iteration)

In fact std::thread::sleep doesn't exist. There's sleep_for and sleep_until. Time deltas and time points are incompatible at the type level, so you have to do:
std::this_thread::sleep_until(std::chrono::system_clock::now() + 300ms)
edit: s/thread/this_thread/
GP's snippet was in Rust (not that I know if it's valid Rust code).
However, in C++ std::thread is a class and it does not have a static member function sleep_until. (However, std::this_thread, which is a namespace, does have such a function).
D'oh! Thanks for the correction! Rust using std:: for its standard library does make some code snippets ambiguous!
