View filter of 'now' not working propery on date (as datestamp)

Created a view filter:
- operator: greater than
- value: now

On a (datestamp) date field (Granularity: year, month and day. I've tried increasing granularity and making the Time zone handling: sites timezone) of a CCK content type.

The view shows no nodes with future dates. If I change the operator to 'less than' then it shows all nodes regardless of the (future or past) date.

If the filter value is an actual date (e.g MM/DD/YYYY like 04/05/2005) then the correct node/s are returned.

So I can only assume there is a problem using now. I've replicated the error on 2 separate servers with different versions of php and mySQL.
I tried the patch at: http://drupal.org/node/122063 because I thought the issue could have been related but it didn't make a difference.

You can view and test the issue here. http://www.bats.co.nz/cms/?q=coming-soon
I've exposed the filter and made nodes editable by anon users. Devel is also on.

If you need login details let me know and I'll email them to you.

Thanks,
