Hello I have a machine I have to take care of I booted it last Wednesday (oct 30), its clock was accurate This morning (nov 06), I saw the date was wrong (didn't get any more cron mails) The time seems to loop in a little 7/8 second interval Let's see that : the following "date" command is send every second (human typing precision :-) [root@machine etc]# date lun nov 3 10:17:50 CET 2003 [root@machine etc]# date lun nov 3 10:17:51 CET 2003 [root@machine etc]# date lun nov 3 10:17:52 CET 2003 [root@machine etc]# date lun nov 3 10:17:53 CET 2003 [root@machine etc]# date lun nov 3 10:17:54 CET 2003 [root@machine etc]# date lun nov 3 10:17:56 CET 2003 [root@machine etc]# date lun nov 3 10:17:57 CET 2003 [root@machine etc]# date lun nov 3 10:17:50 CET 2003 [root@machine etc]# date lun nov 3 10:17:51 CET 2003 as you can see, as soon as time reaches 10:17:57 it jumps back to 10:17:50 (I checked this a whole minute long) I killed almost all running processes, nothing changed (I don't think it's a joking process) I changed time (date --set) the same behaviour repeats with a new time frame (I don't think it's a cron'ed kidding job) I thought it was an RTC problem so I tried to control it by querying hardware clock every second, I got : [root@machine etc]# hwclock jeu 06 nov 2003 17:03:11 CET -0.702771 secondes [root@machine etc]# hwclock jeu 06 nov 2003 17:03:12 CET -0.501165 secondes [root@machine etc]# hwclock jeu 06 nov 2003 17:03:13 CET -0.527763 secondes [root@machine etc]# hwclock jeu 06 nov 2003 17:03:14 CET -0.416451 secondes [root@machine etc]# hwclock jeu 06 nov 2003 17:03:15 CET -0.396386 secondes [root@machine etc]# hwclock jeu 06 nov 2003 17:03:16 CET 7.492503 secondes [root@machine etc]# hwclock jeu 06 nov 2003 17:03:17 CET -0.201150 secondes [root@machine etc]# hwclock jeu 06 nov 2003 17:03:18 CET -0.102207 secondes quite different, rtc is up-to-date and doesn't jump back, but sometime the drift indicated is 7 seconds. I don't know what exactly this number is, but it's confusing to see such a value It's a stock red hat 8.0 machine which I can only administer remotely any clue ??? tia -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
