De acordo com o texto, considera‐se contraditório, em relação
à percepção humana do tempo,
What time isit? Thatsimple question probably is asked more
often today than ever. In our clock‐studded, cell‐phone society,
the answer is never more than a glance away, and so we can
blissfully partition our daysinto eversmaller incrementsfor ever
more tightly scheduled tasks, confident that we will always
know it is 7:03 P.M.
Modern scientific revelations about time, however, make
the question endlessly frustrating. If we seek a precise
knowledge of the time, the elusive infinitesimal of “now”
dissolves into a scattering flock of nanoseconds. Bound by the
speed of light and the velocity of nerve impulses, our
perceptions of the present sketch the world as it was an instant
ago—for all that our consciousness pretends otherwise, we can
never catch up.
Even in principle, perfect synchronicity escapes us. Relativity
dictates that, like a strange syrup, time flows slower on moving
trains than in the stations and faster in the mountains than in
the valleys. The time for our wristwatch or digital screen is not
exactly the same as the time for our head.
Our intuitions are deeply paradoxical. Time heals all
wounds, but it is also the great destroyer. Time is relative but
also relentless. There is time for every purpose under heaven,
but there is never enough.

Gabarito comentado
A relação paradoxal da percepção humana sobre o tempo, uma vez que o tempo tem poder de cura e destruição, é apresentada no último parágrafo.
Our intuitions are deeply paradoxical. Time heals all wounds, but it is also the great destroyer. Time is relative but also relentless. There is time for every purpose under heaven, but there is never enough.
Tradução: Nossas intuições são profundamente paradoxais. O tempo cura todas as feridas, mas também é o grande destruidor. O tempo é relativo, mas também implacável. Há tempo para todo propósito debaixo do céu, mas nunca é suficiente.
