Jiffies + hz / 2
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. WebJiffies + (n * HZ / 1000); future n milliseconds . Assuming that the value of jiffies is 1000, the 3-bit jiffies will overflow in about 50 days. Since the system's runtime can be many …
