[Zope] Timing SQL queries

Is there any support for timing SQL queries made by SQLMethods? For optimizing a site, it's nice to turn on a logging mode, exercise the site a bit, and then look at a log of every query and the time it took; this lets you notice redundant queries (means you need some caching) or unusually slow queries (means you need an index or a table rethink). Any suggestions on how I should implement this, if it's not already supported? -- A.M.
