Answer 1

There is not a direct way to do that from within CQLSH.

There are a certain set of string date formats which can be coerced. See the CQL Timestamp type documentation page for some examples like:

yyyy-mm-dd HH:mm
yyyy-mm-dd HH:mm:ss
yyyy-mm-dd HH:mmZ
yyyy-mm-dd HH:mm:ssZ
yyyy-mm-dd'T'HH:mm
yyyy-mm-dd'T'HH:mmZ
yyyy-mm-dd'T'HH:mm:ss
yyyy-mm-dd'T'HH:mm:ssZ
yyyy-mm-dd
yyyy-mm-ddZ

As a workaround you could modify your CSV file to adjust the date format, then import it. (In your case it may be as simple as "yyyy/mm/dd" -> "yyyy-mm-dd".)
