title: Effect of date type precision on performance
body: <p>At the c++ time libraries(<a href="https://howardhinnant.github.io/date/date.html" rel="nofollow noreferrer">date</a> or <a href="https://en.cppreference.com/w/cpp/chrono/duration" rel="nofollow noreferrer">chrono</a>), does the use high precision type of these libraries reduce performance(memory usage, speed) or is it independent of the type of precision?</p>
  
  <p>high precision type:
  nanoseconds, microseconds, milliseconds, ...</p>
