Is this still an issue in the current Minecraft Snapshot 15w45a or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

I'm really disappointed in this resolution. This lag makes it impossible to speed up server time in a nice-looking way. The sky moves very jerkily and it looks terrible.

If this is going to be left in the game, the resolution should be "Won't fix". I'm pretty sure this lag wasn't added on purpose.

" if "/time add 10" is hooked up to a 20 tick clock ... the sun will jump forward every second or so."

Isn't that expected? 20 redstone ticks is two seconds. So you told it to make the time jump forward slightly (half a second as the time is measured in game ticks) every two seconds.

with 20 tick clock he means 20 hz, which is possible with setblock/fill clocks and repeating command blocks
