> If we define the following column family using CQL3:
> CREATE TABLE useractivity (
>   user_id int,
>   activity_id 'TimeUUIDType',
>   data text,
>   PRIMARY KEY (user_id, activity_id)
> );
> Add some values to it.
> And then query it like:
> SELECT * FROM useractivity WHERE user_id = '3' AND activity_id < '2012-11-07 18:18:22-0800'
ORDER BY activity_id DESC LIMIT 1;
> the record with timeuuid '2012-11-07 18:18:22-0800' returns in the results.
> According to the documentation, on CQL3 the '<' and '>' operators are strict, meaning
not inclusive, so this seems to be a bug.
