Yeah - until now the best was

   update session-state {
       &Tmp-Integer64-1 = "%{expr:(%c*1000) + (%C/1000)}"
   }

at the start of authorize, and then

   update request {
     &Tmp-Integer64-0 := "%{expr:(%c*1000) + (%C/1000) - 
%{session-state:Tmp-Integer64-1}}"
   }

to find the time taken so far. It'll work most of the time, but fails 
randomly because %c and %C are calculated separately.

It makes things much nicer :)

   update session-state {
     &Tmp-Integer64-1 = "%{time_since:ms}"
   }

and

   update request {
     &Tmp-Integer64-0 := "%{time_since:ms &session-state:Tmp-Integer64-1}"
   }

Debian/Ubuntu packages in the freeradius-devel-3.2 repo contain it.
