This folder provides functions that are not part of the standard C library but are part of the POSIX.1 (IEEE Standard 1003.1) standard.
## NOTE
1. For consistency of compilation results across the different of platforms(gcc, keil, iar) , you better use ``#include <sys/time.h>`` to instead of ``#include <time.h>``.
