My user space driver need to call a function:

clock_get_calendar_microtime(&currentTime_sec,&currentTime_usec);

I hope Xcode DriverKit library can include "kern/clock.h"

CLOCK_REALTIME 0 ==> System-wide real-time clock. This clock is supported by all implementations and returns the number of seconds and nanoseconds since the Epoch.

Type of a clock value from clock_gettime_nsec_np(CLOCK_REALTIME). Equivalent to a value from gettimeofday() in nanoseconds.

==> clock_get_calendar_microtime(&currentTime_sec, &currentTime_usec)
