1) In the test window press "Press me" button.
2) Two timestamps should be printed.
3) Verify that they are not differ a lot:
it is okay to observe a 1 or 2 seconds difference.
4) Change the system time significantly (by a month or a year)
by using the OS abilities.
5) Click on the button once again.
6) Printed times should still be the same.
Pay attention to the Month/Year if they were changed.
7) It is okay to observe a 1 or 2 seconds difference and this is not a fail.
8) If the difference is more then 1-2 seconds noticed press fail,
otherwise press pass.
