+CLOCK_GET - Get date and time information
+-----------------------------------------
+.. index:: obtain the time of day

+
+.. warning::
+
+    This directive was removed in RTEMS 5.1.  See also
+    :ref:`ClockManagerAdviceClockGet`.
+
+CALLING SEQUENCE:
+    .. code-block:: c
+
+        rtems_status_code rtems_clock_get(
+           rtems_clock_get_options  option,
+           void                    *time_buffer
+        );
+
+DIRECTIVE STATUS CODES:
+    .. list-table::
+      :class: rtems-table
+
+      * - ``RTEMS_SUCCESSFUL``
+        - current time obtained successfully
+      * - ``RTEMS_NOT_DEFINED``
+        - system date and time is not set
+      * - ``RTEMS_INVALID_ADDRESS``
+        - ``time_buffer`` is NULL
+
+DESCRIPTION:
+    This directive obtains the system date and time.  If the caller is
+    attempting to obtain the date and time (i.e.  option is set to either
+    ``RTEMS_CLOCK_GET_SECONDS_SINCE_EPOCH``, ``RTEMS_CLOCK_GET_TOD``, or
+    ``RTEMS_CLOCK_GET_TIME_VALUE``) and the date and time has not been set with
+    a previous call to ``rtems_clock_set``, then the ``RTEMS_NOT_DEFINED``
+    status code is returned.  The caller can always obtain the number of ticks
+    per second (option is ``RTEMS_CLOCK_GET_TICKS_PER_SECOND``) and the number
+    of ticks since the executive was initialized option is
+    ``RTEMS_CLOCK_GET_TICKS_SINCE_BOOT``).
+
+    The ``option`` argument may taken on any value of the enumerated type
+    ``rtems_clock_get_options``.  The data type expected for ``time_buffer`` is
+    based on the value of ``option`` as indicated below:
+
+    .. index:: rtems_clock_get_options
+
+    +-----------------------------------------+---------------------------+
+    | Option                                  | Return type               |
+    +=========================================+===========================+
+    | ``RTEMS_CLOCK_GET_TOD``                 | ``(rtems_time_of_day *)`` |
+    +-----------------------------------------+---------------------------+
+    | ``RTEMS_CLOCK_GET_SECONDS_SINCE_EPOCH`` | ``(rtems_interval *)``    |
+    +-----------------------------------------+---------------------------+
+    | ``RTEMS_CLOCK_GET_TICKS_SINCE_BOOT``    | ``(rtems_interval *)``    |
+    +-----------------------------------------+---------------------------+
+    |``RTEMS_CLOCK_GET_TICKS_PER_SECOND``     | ``(rtems_interval *)``    |
+    +-----------------------------------------+---------------------------+
+    | ``RTEMS_CLOCK_GET_TIME_VALUE``          | ``(struct timeval *)``    |
+    +-----------------------------------------+---------------------------+
+
+NOTES:
+    This directive is callable from an ISR.
+
+    This directive will not cause the running task to be preempted.
+    Re-initializing RTEMS causes the system date and time to be reset to an
+    uninitialized state.  Another call to ``rtems_clock_set`` is required to
+    re-initialize the system date and time to application specific
+    specifications.
