Since one second is one sixtieth of one minute, and one minute is one sixtieth of one hour, and one hour is one twentyfourth of one day, and one day is one threehundred and sixtyfith of one year, one year is just our earthly measurement of the event of our planet circuling the sun, our rotation of our polanet (24 Hours).
You see, time is a measurement of our solarsystem event, and has no effect on the rest of the galaxy or the universe.
Allso the speed of light is just a reflection on a reflectable surface or by a light emmiting object like the sun.
