############################################

*Probe clock source on demand*

Type: ``bool``

Help
====

.. code-block:: none

    This option is helpful if the driver does not fully support the
    ClockSourceTime.invoke function. If this is enabled, the clock
    source is probed when it is actually needed instead of being
    updated on each tick.
    See IEEE 802.1AS-2011, chapter 9.2 for more details.
