What are the uses of std::chrono::high_resolution_clock?

by

There are none.

Sorry, my bad.

If you are tempted to use high_resolution_clock, choose steady_clock instead. On libc++ and VS high_resolution_clock is a type alias of steady_clock anyway.

On gcc high_resolution_clock is a type alias of system_clock and I’ve seen more than one use of high_resolution_clock::to_time_t on this platform (which is wrong).

Do use <chrono>. But there are parts of <chrono> that you should avoid.

  • Don’t use high_resolution_clock.
  • Avoid uses of .count() and .time_since_epoch() unless there is no other way to get the job done.
  • Avoid duration_cast unless the code won’t compile without it, and you desire truncation-towards-zero behavior.
  • Avoid explicit conversion syntax if an implicit conversion compiles.
