The issue key cannot be changed, you can change the project key but it has to be alpha numeric characters only. If you want to create your own key you need a custom field do some scripting in order to get the key you want using an app like ScriptRunner or Power Scripts

The answer to this is that it is possible, but you will have to re-write (and then maintain) the whole of Jira and all the add-ons you want to use with it. 

So, Mikael is right - you can create a custom field with your date/time and number with a bit of code. 

But I'd like to point out that it's mostly useless.  Your users will quickly start talking in Jira keys because they offer a simple unique identifier that gives them immediate information, instead of having to think about when something was created.  (This seems like an incredibly poor choice of identifier for issues, part of me is curious about how you'd come to think you want such a poor scheme?)

Dear's

Thanks to your support . in our organization, jira wants to replace with software that has the same identifier and user like this way .

could you explain me how can  change them?

I'm not sure you understood the point I made.  Could you re-read the first sentence and confirm that really is what you want to do?

[Mehran Namdar]

I understood your answer. But as I know the key in jira has many features that are not in the other field

Can i have this feature in issue key ?

Let me try this again, and keep it simple:

You will have to re-write (and then maintain) the whole of Jira and all the add-ons you want to use with it.
