The 'adjkerntz -i' run at boot[1] should adjust for a TZ update occuring overnight, assuming CMOS has local time (ie /etc/wall_cmos_clock exists) [1] actually run when going to multi-user, so with CMOS set to local time, you should remember to run 'adjkerntz -i' when working in single user mode (eg make installworld) if you want correct file timestamps. cheers, Ian _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
