The JSON encoder will handle escaping for you, so colons, quotes, backslashes
or whatever aren't an issue.
What's happening here is that you have a 'DateTime' object, and the JSON
encoder is puking on encoding it, as it's an object.
DateTime objects stringily by default, which is why you get: encountered object
'2012-02-29T17:16:27'.. This error message is crap really - it doesn't make it
clear that it's an object which has been stringified, and doesn't tell you
which class is at fault!!
So, the simplest fix is:
> cell => [

Adding the ."" means that the object gets explicitly stringified, using
whatever the default formatter is (giving you something ISO8601ish by default).
You can, of course, be a little more creative / flexible with the formatting if
you want or need to be - checkout the DateTime::Format docs :)
