DateTime in to_xml returns GMT from 3.0.2

Ticket from 24.11, but no replies yet:

Rails 3.0.1 to_xml: 2010-11-18T14:41:30+01:00

Same code in 3.0.2 and 3.0.3: 2010-11-18T13:41:30+00:00

So the time is correct off course, but shouldn't this output according
to chosen timezone as earlier?

to_json in 3.0.2 returns local timezone as before.

I think I have a similar ticket on my plate so I'll take a look at this.
Would you mind adding a more complete reproduction, like an irb session
or something?
