    <title>Time management</title>

    <para>

    Time is one of the dimensions in which kernel, as well as the whole system, operates.

    It is of special importance to other kernel subsytems. Knowledge of time makes it possible

    for the scheduler to preemptively plan threads for execution. Different parts of the kernel

    can request execution of their callback function with some specified delay. A good example

    of such kernel code is the synchronization subsystem which uses this functionality to implement

    timeouting versions of synchronization primitives.
