I added the --no-use-server-timestamps option to both FETCHCOMMAND and RESUMECOMMAND variables in /etc/portage/make.conf, then removed everything in /usr/portage/{distfiles,packages} and finally did emerge -e @world. Now timestamps seems to be good and compatible with eclean's --time-limit option. Thank you Neil!
