It's the time after processing each set of files, i.e. the value you have -n set
to on the sks build command line. On a 1.5G Hz Sempron box with 1GB RAM, I can
load just under 200,000 keys per pass without starting to swap. So, if I'm using
a dump from pramberger.at where each file is 25k keys, I use -n 7. From
linux.prato.it, each dump is 15k keys, and then I use -n 13.
ls -ltu on your dump directory will tell you the last access time for each file.
Add -r and you'll easily get the last file read in.
build takes about 6 hours on this box and pbuild approx 2.5 hrs.

I don't know that this has ever been measured. I've never built with fastbuild

I guess that could be done, but it would be significantly larger than the
existing key dumps.
