The timer reaches zero in this episode. When the timer reaches zero, the clock switches to a series of Egyptian hieroglyphics. The first three places are red color on black ground, the last two digits are black colored on red ground.
Only the first, third, fourth and fifth symbol are visible before the timer is reset in the very last moment:
Digit 1 is Egyptian for S (cloth) Digit 2 is not shown Digit 3 is Egyptian for D (firedrill) Digit 4 is Egyptian for AH (vulture) Digit 5 is an Egyptian death symbol (dead man)
Note: The text reads from left to right. A possible translation can be found on lostpedia.com and proposes "Die" or "to die" or "to kill" as a translation if one assumes a spiral shaped glyph in the second Digit.
