## Detailed Description

This is a Standard C++ Library header.

Definition in file chrono.

## Typedef Documentation

## high_resolution_clock

using std::chrono::_V2::high_resolution_clock = typedef system_clock

Highest-resolution clock.

This is the clock "with the shortest tick period." Alias to std::system_clock until higher-than-nanosecond definitions become feasible.
