As a sentence it means - I was only gone for a short while. As a saying - it means - How did you get yourself in this mess while I was just gone for a while. Example - A mother leaves her kids playing in the living room while she cooks lunch. She comes back 30 minutes latter and the room is a mess. She cries in despair "How did you do this? I was only gone for a minute!!!" As a saying it does not indicate an amount of time, but an amount of anger or disbelief.
