How does everyone edit clock in/out mistakes?

We are just starting SCM and will be switching from our current time tracking software to the one included in SCM in order to better track labor hours.

My question is, since you are unable to adjust clock in and clock out times, how do you fix the mistakes that inevitably happen from your employees? Our current software lets me go in and adjust times when the employees leave me a note but that isn't an option in SCM so I need another method. 

What does everyone here to to address this?
