It sounds like the original request "I need to add the time spend for a particular Flow to a Logfile" wants to track the 'login time' in milliseconds. I suppose one could track the time from receiving the original request to sending the authentication - or receiving the accounting packet after authentication.. but I seriously doubt the added granularity would have any real meaning. (References gettimeofday(2) for the seriously nerdy)

Sounds like you'd need to write your own additions to FreeRadius and submit them as an enhancement. (I doubt the result would be worth the effort.)

I see it useful too, when specifying for example "response_window" that instead of be 1 "One second" could be 1200 as in "twelve hundred milliseconds".

I have found some devices that time out in 3 seconds , in these cases you still want to retry at least once . Of course here the network delay is kept under 300 milliseconds end to end.

This is impossible.

The dates and elapsed times in RADIUS have a resolution down to one
second, but no more.

It's possible to "fake" adding milliseconds, but they will bear little
relation to the actual session times. Network delays, processing
delays, etc. will all affect the results.
