ModSecurity has a few additional timers as well. They do not 
appear in the documentation, but are covered in Ivan Ristic's
Apache Security Book, p. 184f.
They allow you to time the request on a reverse proxy and
on the backend seperately within the RP's access log.

It boils down to the following:

LogFormat: ... %D %{mod_security-time1}n %{mod_security-time2}n %{mod_security-time3}n ...

Afterwards you do calculations on these values.
