The Unknown Poem

The clock remembers what the key forgot.
A shadow writes answers beneath the hour hand.
Every minute hides another question.
I found a note signed "emit".

The lock opened, but the room remained closed.
A name appeared in the dust: WONKNU.
The silence said the mystery was already solved.
Yet every clue pointed forward.

Yet every clue pointed forward.
The silence said the mystery was already solved.
A name appeared in the dust: UNKNOWN.
The lock opened, but the room remained closed.

I found a note signed "time".
Every minute hides another question.
A shadow writes answers beneath the hour hand.
The clock remembers what the key forgot.

Solution: "racecar", First the peom above is a palindrome revealing new Hint. And on hint page it says "stressed" reversed to "desserts", revealing second hint. And on the second hint you will see some texts blinking. Which is reverse base64 encoded of racecar.
