| 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. |
