On UP2000, time gets lagging behind, while on LX164 with AlphaBIOS, time gets faster about a minute a day compared to two other Linux boxes with Intel CPUs. On both Alpha machines with SuSE-6.4, I started /etc/rc.d/xntpd at boot time. Had checked the time right after boot, both clocks were reset correctly to clock of the xntp server as expected. What is responsible for this error? The real-time clock of each machine or the kernel? RTC support has been enabled on the kernel config on every machine. Best regards, G.
