How does the AFAttribute.GetValue(AFTime) method retrieve attribute values?  I.e. suppose you were to request the value of an attribute for the time *-8h, but there wasn't a value at that specific time, would the call return an interpolated value, would it use an AtOrBefore retrieval method, or would is it looking at the exact time?
