Get current time
================

.. toctree::
	:hidden:

Check that current time can be obtained from PTP device associated with the tested network interface.

Scenarios: X3-PTP002.



#. Find out PTP device associated with the IUT interface, call **open()** to get its FD.

#. Call **clock_gettime()** with PTP device FD to get the first timestamp.

#. Sleep for a while.

#. Call **clock_gettime()** with PTP device FD to get the second timestamp.

#. Check that difference between the obtained timestamps corresponds to the delay between **clock_gettime()** calls.
