Time units

Userspace exposed time units

zx_time_t is in nanoseconds.

Use [zx_clock_get_monotonic()] to get the current time as the number of nanoseconds since boot.

Kernel-internal time units

lk_time_t is in nanoseconds.

When writing code that will run in the kernel, to read the current monotonic clock value, use:

#include <platform.h>

lk_time_t current_time(void);

zx_clock_get_monotonic()
