I agree, so my questions are: - what is your TZ? - what does "[/bin/]date" show? - what does your hardware clock: "/sbin/hwclock --show" report? [need to be root to use that command] - is your /etc/localtime file a standalone file or a symlink to /usr/share/zoneinfo/... ? - if a symlink, to what file? - what is the timestamp on the localtime (or what it's symlinked to) file? - what does "zdump -v /etc/localtime" return ? i.e., is it for the correct TZ?
