how the get the time used for every http request in micro-second

hi, all
now, i want to get the time used for every user's request in order
to evaluate the performance of our background data modules.
we can use the %T argument of ap_config_mod to print this time
used in second at present. but in practice, the time used for most of
the requests are less than one second. so, we want to get it in a more
precise in micro-second just using the struct timeval.
is anyone can give me a help. thanks so much.

This is a basic Windows API question, and not really related to web servers.

Anyway, without knowing what programming language you want to use it is
just a guess on my part. So, since I am primarily a C programmer, I will
answer in C: Use _ftime() or GetSystemTime().
