The debug screen displays sl=15 at night. I think that's incorrect.

Anyone coming here and wondering why it's Works As Intended, here is a comment from a very old ticket:

Minecraft has two light values: sun light and block light. The sun light value never changes as that would be very expensive. This is how it worked before beta 1.8 and sunrise/sunset were laggy.
The game knowns to ignore sun light values during the night for spawning and such so there is no problem with this setup. It even uses the sun light values for deciding where and how intensely it should render the blue "moonlit night" shade for a world instead of just pitch black darkness.
Don't think so because
sl:shows the maximum possible skylight exposure level at the spot you are standing. For my thinking,rl:should instead change at night here. However, this has already been reported in [MC-911|MC-911] and some linked reports.
