Oh I might as well get in on this childishness too. Snitty is as snitty does. Na na na na na! Well, that really was fun.
the thing is he only does if for effect when he has an audience, such as yourself, he can be reasonable, and he has shown that he can understand concepts such as these even if he rejects them for, what I would consider, silly reasons.
But when he has a audience it sort of brings out the worst in him.
Where is this information located? And how long does it take a zircon to go around the earth? and what the flip is a zircon anyway? And what does it matter in the scope of life?

that particular information is located in many hundreds of locations across the internet. I would suggest typing "oldest zircon" into a search engine.
A zircon doesn't go around the earth it is a crystaline mineral that is found in small quantities in the rocks of the earth.
If you meant how long does it take a zircon to go around the sun; then it takes exactly the smae amount of time as anything else on the eazrth, it takes a period off time we label as one year which is by definition the amount of time it takes the earth, and everything on it including zircons, to orbit the sun.
A zircon is the chemical ZiSiO4 Zirconium sillicate, a mineral made up of Zirconium, Silicon and Oxygen. It is useful for dating because small amounts of Uranium will be included in Zircon crysltals but no lead at all can be taken up by that crystal structure. Uranium exists in isotopes that break down to lead when they decay. If you measure the amount of lead that is found in a zircon relative to the amount of Uranium you can get a pretty accurate measurement of when that crystal was formed, that is is accurate to within a few dozen million years.
Zircons are very hard and chemically inert and so they are like little clocks that tell us when they were formed. the oldest ones found so far date to 4.4 billion years old.
That is pretty irrefutable evidence as to a minimum age for the earth. You have to break the laws of physics to make a scientific case for it not being accurate, and invoke a deceptive god if you don't wish to do that.
Most creationists try to suggest that "things were different in te past", thus ignoring the evidence that shows that radioactive decay rates haven't altered in at least 2 billion years such as the Oklo natural nuclear reactor.
What does all that matter? Not a lot to me, rather a lot if you are trying to cling to YEC. But it is nice to know.
