A classic metering error. The meter is attempting to make everything average to 18% grey. If it's dark - I mean really dark, as in hours after the sun sets - you'll get an overexposure. That's what you got here. In these cases, one has to know that this is going to happen and dial in a stop to two and a third stops of underexposure, at least if you want it to look like what you see. You may not.
