Web15 apr. 2003 · Because of the inability of the PIT to actually generate an accurate 1/HZ interrupt, the wall clock is updated with a more accurate value (999848 nanoseconds per jiffie for HZ = 1000). This causes a 1/HZ interpretation of jiffies based timing to run faster than the wall clock, thus causing sleeps and timers to expire short of the requested time.
