Apache 2.4 introduced sub-second granularity for log timestamps, so you can do things like
LogFormat "%{%d/%b/%Y %T}t.%{msec_frac}t %{%z}t [...]
As far as I can tell, this feature is not available natively in Apache 2.2. We're not ready to upgrade to 2.4 yet, but I'd still like to have granular timestamps.
Is there a way of getting this functionality in Apache 2.2?
The documentation says this feature should exists in apache 2.2
take a look at http://httpd.apache.org/docs/2.2/mod/mod_log_config.html.
