ktime_get_boottime - Returns monotonic time since boot in a ktime
Returns the monotonic time since boot in a ktime
This is similar to CLOCK_MONTONIC/ktime_get, but also includes the time spent in suspend.
Definition at line 1231 of file timekeeping.c.
ktime_get_monotonic_offset() - get wall_to_monotonic in ktime_t format
Definition at line 1369 of file timekeeping.c.
ktime_get_real - get the real (wall-) time in ktime_t format
returns the time in ktime_t format

schedule_hrtimeout - sleep until timeout : timeout value (ktime_t) : timer mode, HRTIMER_MODE_ABS or HRTIMER_MODE_REL
Make the current task sleep until the given expiry time has elapsed. The routine will return immediately unless the current task state has been set (see set_current_state()).
You can set the task state as follows -
TASK_UNINTERRUPTIBLE - at least time is guaranteed to pass before the routine returns.
TASK_INTERRUPTIBLE - the routine may return early if a signal is delivered to the current task.
The current task state is guaranteed to be TASK_RUNNING when this routine returns.
Returns 0 when the timer has expired otherwise -EINTR

schedule_hrtimeout_range - sleep until timeout : timeout value (ktime_t) : slack in expires timeout (ktime_t) : timer mode, HRTIMER_MODE_ABS or HRTIMER_MODE_REL
Make the current task sleep until the given expiry time has elapsed. The routine will return immediately unless the current task state has been set (see set_current_state()).
The argument gives the kernel the freedom to schedule the actual wakeup to a time that is both power and performance friendly. The kernel give the normal best effort behavior for "@expires+@delta", but may decide to fire the timer earlier, but no earlier than .
You can set the task state as follows -
TASK_UNINTERRUPTIBLE - at least time is guaranteed to pass before the routine returns.
TASK_INTERRUPTIBLE - the routine may return early if a signal is delivered to the current task.
