Document of WRITETIME function needs update

Hi,

I found that the WRITETIME function on counter column returns date/time in
milliseconds instead of microseconds, which is not mentioned in the document
<http://www.datastax.com/documentation/cql/3.1/cql/cql_using/use_writetime.html>.
It will be helpful to clarify the difference in the document.

One side question: I denormalize the counter column value to regular tables
using read-after-write in QUORUM consistency from counter table and update
the regular tables using counter column's write time to resolve write
conflict. Is this a valid use case?

Thanks,

Ziju.
