come on time

This goal has the following fine print specified by scarabaea:

I measure the number of minutes by which I was late to the classes I conduct. Positive numbers mean I was late by than number of minutes. If I come beforehand, I can enter negative numbers gaining me back some of the late time. But no more than 5 minutes per occasion.
The excuse "students were not there yet anyway" is not accepted if they hadn't informed beforehand that everyone will be late.
