297 * profiling virtual time timers are kept internally in the
298 * way they are specified externally: in time until they expire.
300 * The real time interval timer expiration time (p_rtime)
301 * is kept as an absolute time rather than as a delta, so that
302 * it is easy to keep periodic real-time signals from drifting.
304 * The real time timer is processed by a callout routine.
305 * Since a callout may be delayed in real time due to
307 * time callout routine (realitexpire, given below), to be delayed
308 * in real time past when it is supposed to occur. It does not
309 * suffice, therefore, to reload the real time .it_value from the
310 * real time .it_interval. Rather, we compute the next time in
311 * absolute time when the timer should go off.
333 * If time for real time timer has passed return 0,
334 * else return difference between current time and
335 * time for the timer to go off.
477 * If time is not set up to reload, then just return.
478 * Else compute next time timer should go off which is > current time.
641 * Return the best possible estimate of the time in the timeval
728 * ratecheck(): simple time-based rate-limit checking.
