Hi all,

```
i got a record from my project server side database, like this :

    @user = User.find 1

```

then i cover @user to json format:  
@user.to\_json

the result :  
“created\_at”: “2009-01-28T12:29:32Z”

what’s the T and Z of created\_at field ?

but i change Rails 2.2.2 to Rails1.1.6,

I got :  
“created\_at”: “2009-01-28 12:29:32”

this is a bug of the Rails2.2.2 ???

See RFC3339.

I would call it an improvement. “Z” means UTC, but you can convert to  
and use other timezones if you wish. The old way gives no clue as to  
timezone and is therefore incomplete.
