Congolese Time

It is pretty funny out here in the Congo. Mostly doing with time. I have a group of students that take karate with me. I told them one day to come at 3 PM. They showed up after 4, after I was done teaching. So I told them to come in three days. They didn't even show up. So then when they did come, I told them to come today between 9 AM and 10AM. They showed up at 8 AM?!! At least they showed up today.
