I'm a little confused.  The gettimeofday()/apr_time_now() happens in the httpd 
core AFAIK.   Brian Pane said that it's cheaper than time() on some platforms, I 
believe.  If we want to discuss alternatives to that, the discussion belongs on 
dev@httpd

But then in your next post it sounds like you're experimenting with the time() 
syscalls in mod_specweb99.

Which spec?  If you are referring to either the SPECWeb99 run rules or to 
RFC2616, neither of them dictate which syscalls you use.
