If you're looking to eek a few extra minutes out of your lunch break and would also enjoy tricking your boss in the process, this is for you: a clock that slows down to boost the 12pm hour by 12 minutes every day.
This magical clock speeds up by 20% at 11am and slows down by 20% at 11:48am, giving you an extra 12 minutes of lunch. That's because when it's really 12pm, the clock will read 11:48. By 1pm, it'll be caught back up and all will be right with the world. Just hope your boss doesn't own a watch.
