Hi, I have a box of RedHat 8.0 whose MB is intel se7500cw2 (with promise PDC20267). It have been running ok some days ago. But these days i find the shift between system clock and hardware clock is very obvious. I have done some operations as follows: [root@xxx bin]# clock -s;date;clock Mon Jul 7 23:07:42 CST 2003 Mon Jul 7 23:07:45 2003 -0.115744 seconds after 10min: [root@xxx bin]# date;clock Mon Jul 7 23:11:56 CST 2003 Mon Jul 7 23:17:22 2003 -0.486481 seconds Every day the shift can be 12 hours and again !!!! why? many thanks. --http://www.eyou.com --Îȶ¨¿É¿¿µÄÃâ·Ñµç×ÓÐÅÏä ÓïÒôÓʼþ Òƶ¯ÊéÇ© ÈÕÀú·þÎñ ÍøÂç´æ´¢...ÒÚÓÊδ¾¡ -- Psyche-list mailing list Psyche-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/psyche-list
