The distance from the Earth to the Sun varies because the Earth's orbit around the Sun is elliptical. So the time will vary by about 3% depending on the Earth's distance from the Sun. The average is about 497 seconds, or 8.28 minutes, or 8 minutes 17 seconds.

The time taken for the journey (from the Sun's surface to the Earth's) will vary between 8.14 and 8.42 minutes, which is 8 minutes 8 seconds at perihelion and 8 minutes 25 seconds at aphelion.

Calculating the Time
The semi-major axis of the Earth's orbit is 149,598,261 kilometers, less the maximum radius of the Sun (695,500 km) and the Earth (6378 km) gives the distance from the Sun's surface to the Earth's of 148,896,383 km. At the speed of light, 299792.458 km/sec, light takes about 497 seconds to travel this distance.
