You will find a handful of lines that contain 2008-01-* which is quite clearly outside the range given. I am looking for values between November 2nd 2008 and November 4th 2008.
You can even grep 2007 and you will find many entries that aren't even in the same year that I have specified.
This is a problem. Now I can go ahead and double check the dates against the desired range. I can very easily exclude the January dates when the range is for November. But how do I know that I am actually getting all the results and not just a subgroup?
