The strange thing is that the system date is correct, but is shows wrong date to regular users and correct date to root (and only for root as far as I can see). This sounds to me like one of the two have the TZ environment variable set in the environment and the TZ variable is different from the system default value. echo $TZ Use 'env -i' to force an empty environment and remove any influence from it. Does this give the correct time? env -i date -R Some combination of these things are probably the problem. If the problem is the TZ variable then this simply needs to be found where it is being set and removed. If the problem is the system time zone then reconfiguring /etc/timezone for the correct timezone. If the system time itself is off then setting the system time may be needed. Running NTP to keep the clock updated is recommended. Bob ___ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
