* @brief Native CPU periph/timer.h implementation
*
* Uses POSIX realtime clock and POSIX itimer to mimic hardware.
* This is done with the timer_settime(3), timer_create(3) interfaces, which are
* sometimes found only in the -lrt library, and not in glibc.
*
* This is based on native's hwtimer implementation by Ludwig Knüpfer.
* I removed the multiplexing, as ztimer does the same. (kaspar)
