In CC the maintainer of chrony.
Today I discover this bug-report. (#676454)
The change in /etc/default/rcS from util-linux breaks chrony also.
See my bug report "chrony postinst fails to recognize UTC hardware clock"
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=680498
P.S.
(You can answer in private at the above questions).
I am a newbie of bug report.
Maybe the bug was not of chrony but only of util-linux?
Had I to do a better search in the bug report before open my bug against
chrony?
