Once the system boots, a clock on the CPU itself is the only one Linux cares about for time of day. If NTP is enabled, it uses other sources on the local net or Internet to help keep the CPU clock rate correct. So dead motherboard "hardware clock" battery wouldn't explain issues with the CPU "system clock". -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu http://www.math.clemson.edu/~mjs
