RTC Querying "dc:created" for a specific month/year

Hi,

I was wondering if it is possible to query for all work items for the month of say February.
OR querying for the year and month of 2011 February.  (Encompassing all and only the days of February)

I know the TimeStamp attribute uses the following querying syntax.

In addition to a RFC3339 value, relative times can be used: {[-]number[min|h|d|m|y]} E.g. {-1h} would refer to "our hour ago"

However, I don't see an easy way of doing what I've stated above.
Does anyone have any ideas?

If this isn't supported, please let me know!

Thanks.
Benson
