Why not try to defeat the supposed artificial timer to probe for it's existence? Clock or firmware reset maybe?

It's always a good idea to shade cameras from direct sunlight not only because of overheating of the camera itself, but because I've also seen lenses become damaged from heat. Sometimes the bonding agent between elements can become cloudy after exposure to high heat. You should also not leave your equipment in the trunk of your car in extreme heat for this reason.
