   BTW, timer_gettime use pt_delay(https://github.com/apache/incubator-nuttx/blob/master/sched/timer/timer_gettime.c#L71-L91):
   ```
   int timer_gettime(timer_t timerid, FAR struct itimerspec *value)
   {
     FAR struct posix_timer_s *timer = (FAR struct posix_timer_s *)timerid;
     sclock_t ticks;
   
     if (!timer || !value)
       {
         set_errno(EINVAL);
         return ERROR;
       }
   
     /* Get the number of ticks before the underlying watchdog expires */
   
     ticks = wd_gettime(&timer->pt_wdog);
   
     /* Convert that to a struct timespec and return it */
   
     clock_ticks2time(ticks, &value->it_value);
     clock_ticks2time(timer->pt_delay, &value->it_interval);
     return OK;
   }
   ```
