This directive creates a timer which resides on the local node. The timer
has the user-defined object name specified in ${.:/params[0]/name}. The
assigned object identifier is returned in ${.:/params[1]/name}. This
identifier is used to access the timer with other timer related directives.

notes: |
The processor used to maintain the timer is the processor of the calling task
at some point during the timer creation.
For control and maintenance of the timer, RTEMS allocates a
${/glossary/tmcb:/term} from the local TMCB free pool and initializes it.
