I'd say it's a problem with how the game handles a texture pack. If it was solely the texture pack, then removing it should have given the correct UI. It didn't, so the game isn't doing something right.

(a link to the texture pack just might help someone confirm, test or fix this)

Unmodded? Turning off Terrain Animation in OptiFine (at least in my version) will cause the clock to stay at noon.
