What is everyone's thoughts on the best time of day to fish for walleye?

I typically go out early as the sun is rising if I can get up early enough. But I have often thought about heading out in the afternoon and fishing into early evening before the sun sets. Rather not return to the dock in the dark.

I know the conditions will vary and there is no hard rule for success. Sunlight, water clarity, wind, etc all influences the bite.
