Can you point out where the extra pixels are? I can not see any extra comparing to image of a clock I uploaded.

It's at the bottom of the clock
There does appear to be an extra row of pixels along the bottom!

Still exists in 0.14.1

Confirmed for 0.15.0 on Windows 10 Edition. This also affects item held in-hand and in the inventory, but not as an item entity. It's actually slightly worse than that: not only is there a row of extra pixels on the bottom, but the top is missing a row a pixels, which happen to be the ones added on the bottom. It looks like the texture is being displayed slightly offset, with the top row of the texture wrapping around back to the bottom when rendered. All that needs to be done to fix this is simply remove the offset.

Ugh this bug still happens when you're in the Nether. Reopening.
This pixel appears only at certain times of the day. It was reported again for a fix.
