I'm doing some bitcoin address collections. If there are some meaningful letters in the address or if the address is created in a meaningful time to me, I will buy it.
How can I know when the address is created?

2What do you mean by "I will buy it [the address]"? – Chuck Batson Dec 17 '14 at 03:32

1@Chuck Batson I will pay him for sharing the privatekey,of course I will never use the address for transactions,that would be stupid. – Willipm Dec 17 '14 at 03:36

Addresses are not created, per se. They're simply a representation of a public key. So, you cannot know when an address is "created."
However, it is possible to know the first time an address is used.

2Maybe it's more accurate to say that it is possible to know the first time a transaction that moves outputs from/to a specific address is broadcasted (by querying the mempool) and the first time the same transaction is included into one or more blocks (by parsing the blockchain), as a newly-generated address can be used by an offline-generated transaction but we'll never know it unless it is broadcasted to the network, which can take any arbitrary amount of time. – Dec 17 '14 at 05:48
