One of the most common versions I’ve seen is managers being able to “correct” employees punch in and punch out times. Useful if you forgot to clock in. However, often used to always chop off extra minutes accumulated from being there a few minutes early (“on time”) and staying a few minutes past your shift (until someone else can take over). But don’t you dare to be a few minutes late because you will get some points on your record and risk disciplinary actions.
