Idle time is detected by computing the time spent in the idle thread. There is one idle thread per processor. The idle threads run when there are no executable threads. When a clock interrupt occurs, a clock tick is attributed to the active thread. When this occurs while the idle thread is active, the time is counted as idle time.
