How to get data which has changed within x minutes using CQL?

[Check Peck]

I have a table structure like below -

    CREATE TABLE client_data (
      client_id int,
      consumer_id text,
      last_modified_date timestamp,
      PRIMARY KEY (client_id, last_modified_date, consumer_id)
    )

I have a query pattern like this - Give me everything for what has changed
withing last 15 minutes or 5 minutes? Is this possible to in CQL with the
above tables?
