I'll accept my ignorance here, but there has to be some time element to light otherwise it would have infinite speed.

Relativity: from our perspective, light moves at 300 000 km/s; from light's own perspective, it actually moves at infinite speed.

Which by the way is a reason why you can never reach the speed of light; because it would mean reaching (from your own perspective) an infinite speed, and you can't do that by burning a finite amount of fuel.

Light has infinite speed. Zero time passes for it to move from one place to another, even if it looks like millions of years to us.
