named query log rotation based on time, not size

[Jeff Johnson]

I am currently rotating my named query logs on size, but would like to
be able to rotate the files on the hr, not on the size of the file.
Does anyone have a solution for this ? Im running bind 9.3.2 . I was
thinking I could maybe do something in cron, or something with a
symbolic link, but am getting stuck coming up with a solution.

Thanks

Jeff
