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.
