Date and Time

cat-date-and-time

Manage the complexity of dealing with the fourth dimension.

There are two key libraries:

  • chrono⮳: a comprehensive, full-featured, yet complex date and time library.
  • time⮳: a smaller, simpler library with limited functionality.

There is no clear answer as to which is best between time⮳ and chrono⮳. Evaluate for yourself between these two, but both are trusted and well-maintained.
