Oh please...you do realize that the probably figured okay we've gone out 2000 years that should be more than enough years to calculate out for now when we get closer to 2012 we'll calculate more. You don't think that modern people were the first to corner the market on laziness now do you? I can tell you that in the data warehouse I'm building right now we are only pre-populating the time dimension out 10 years and you know why? Because we can go back and add more later. Same thing with an effective end date...setting to 1/1/3000 it's far enough out in the future that we won't have to care if we didn't set it high enough.
actually, it's much more complicated than that. They had a value for a long amount of time and there were 13 of them in a cycle. 13 of that unit from the begining date of that calander ends on the winter solstice of 2012. But it's still funny to think that the world might end on my birthday.
