About 20 000 years. The main form of heat transport in the Sun is radiation, not conduction or convection. The deep interior of the Sun is so dense (up to 98 grams per cc), that the gamma rays generated in the core bounce from nucleus to nucleus in a random walk, instead of shooting out in a straight line. At each collision they lose a little energy so their wavelength increases. By the time they find their way to the surface mostly they're visible light.

A million years, I think. The high energy light in the form of gamma rays in the sun's core bounces around in random patterns and eventually works its way to the surface. Most of the high energy light that finally makes it to the surface has deceased in its energy level to where it's in the visible light spectrum (low energy light), along with ultraviolet radiation (light with a bit more energy). After a million years journey to the surface, it takes about 8 minutes to reach us.

Somewhere in the area of a million years.

i don't remeber the exact number. but it was some thing like some thousand years. i'm sure that it takes more than 10 years!
