Key.last_modified is None

[lucian1900]

On all keys I create, last_modified appears to be None, instead of the dates boto exposes.

Btw, from what I've seen:

For listing, the format is iso8601 without a timezone
For keys, the format is HTTP Date (RFC 822) with a GMT timezone

Pretty sure I did it right. Crazy that they have different formats.

In case I need to come back to this ticket later: boto/boto#466

Very nice, thanks! :)

[edit]
I think they're different formats because boto relies on the date in the HTTP headers for key GETs, but in listings it uses the explicit date in the content, and I assume amazon's default is iso8601.
