A clock puncher is someone at a job who is eagerly anticipating the end of the work day and will do almost anything to waste time, not do his/her work and then immediately leave at the time they are supposed to, or immediately following the day's departure of their boss.
Mikey pissed the day away doing no work and then immediately left right after his boss did. What a clock puncher!
