The point of having a kernel version date that is related to the source and not to the build-date is to have an idea of what source versions might contribute to a bug. It doesn't matter whether all the source is there or not, whether they're alpha/pc98/sparc or whatever. If we use latest date in a $FreeBSD$ tag of the source files that are installed by submitting the output of 'uname -v' and a kernel config file it's possible to know the latest change in the repository that might have caused a problem. That solves the problem surely. % uname -v FreeBSD 5.0-CURRENT[20011101-12:01:00] #0: Tue Jan 22 09:46:56 GMT 2002 = joe@genius.tao.org.uk:/usr/obj/usr/src/sys/GENIUS=20 This clearly says that the latest change in the repository that could make a difference was on Nov 1st 2001. The Jan 22 date is totally arbitrary. Also it doesn't take too long to do a find across src/sys, compared with the amount of time it takes to build the source. For most users they won't notice it; for power users like us we can switch it off in /etc/make.conf and save the time.
