Does someone keep track of how long it takes to buildworld/kernel?

Some "manual copy & paste" data from the past (original post
is from 2008, repost from 11/2015):

FreeBSD 5 on Pentium 4 with 2 GHz and 1 GB RAM:

(...software advance happens here...)

FreeBSD 7 on Pentium 4 with 2 GHz and 1 GB RAM:

b.world+b.kern:	16574.070u 2516.128s 6:06:03.90 86.9% (with debug)
		18232.967u 2427.404s 7:19:49.24 78.2% (with debug)

buildworld:	11457.047u 2151.158s 3:54:15.31 96.8%
buildkernel:	 3289.368u  529.669s 1:05:25.90 97.2%
		 3503.732u  524.399s 1:11:05.53 94.4%
		 4032.019u  572.636s 1:58:29.08 64.7% (with debug)
installkernel:	   17.396u   12.587s    0:46.89 63.9%
		   18.890u   12.131s    1:11.85 43.1%

As you can see, 5 hours was a possible value on a single-core
single-threat slow-as-ass CPU. But then the system became more
advanced, and 7 - 9 hours compile time became possible. :-)

Sadly I don't have a "copy" of my build time on my current
home PC, including a Core 2 Duo 4600 with 1.8 GHz and 2 GB RAM,
using a SATA disk, with FreeBSD 8-STABLE, but I think it was
around 5 hours for everything (including a custom kernel).

It would be nice if the build system would automatically issue
a log file or at least log message about build time and usage
statistics. If it wouldn't tell about my brain's age, I would
politely ask to have a "flower box"... ;-)
