When a person's life is defined by what time it is.

These people work in extremely structured intervals and never waste time. One may wonder what will become of them if a large-scale worldwide catastrophe were to occur. Their agenda and a clock are their best friends, leaving little room for an actual social life.

It is a well-known fact that most college/university students live their lives like this, making campus a very depressing place to be.
There is a definitive line between being a clock zombie, and having 1-2 weeks of hardcore study sessions berore a test.
girl: "Hey, wanna go out tonight?"

guy: "Sorry, can't... I have to study for roman civilization for the midterm."

girl: "Isn't that midterm like, 4 weeks from now? Wow, you're such a clock zombie."

Get the clock zombie mug.
A clock that, after having been bitten by a zombie, uses blood-coagulation rates to calculate approximately how long until you will become a zombie. When the clock finally counts down to 0:00:00, you are craving brains.
Better pull that trigger before her zombie clock hits zero....
