According to Astrophysics, the photon does not experience the passage of time , so their time must be zero as stated earlier .... see the quote below:
Question:
How does a massless body traveling at c "perceive" the universe? Would length contraction be infinite as well as time dilation and thus the body be everywhere at once?
Answer:
It's rather anthropomorphic to talk of how a photon "perceives" the universe, but.... Since the spacetime interval along a lightlike trajectory is zero, there is zero proper time. The photon does not experience the passage of time (or space for that matter). The entire worldline of the photon simply is, from its beginning to its end (e.g. from the emission of the photon to its absorption).

well sweetie I think what do you mean that there time is zero? Light moves at very close to 300 meters per second. That is very very fast, but it is not instantaneous. It does take time for photons to move, it is just so quick it is meaningless in a non-scientific framework.i hope this helps . B

Propagating photons (aka. gentle) continuously commute at c. digital photons (people who reasonable the EM tension) have not got a c shrink. "is it the fee of a photon it is c, or the fee?" The shrink is the magnitude of the fee. many times referred to as a speed. "if the fee of a photon became c, then the extra advantageous distance travelled in its oscillation could recommend that it travels further, for this reason exceeding c." What "oscillation"? We those that have gentle bypass us, form gentle as oscillating EM waves. yet in a God-like way, if we accompanied alongside with the sunshine, we'd anticipate see a static EM container. The "oscillations" are extra useful considered merely "clusters of photons". A batch orientated "up", a a million/2 wavelength in the back of a batch orientated "down"... and not too lots in between.

That's pretty much true. All things that happen to a photon from its creation to its destruction 'seem' to happen all at the same 'time' as far as it's concerned.

Yes. In its own time frame zero time passes.
However, this is hotly disputed as this entertaining discussion shows.
