The problem here isnt that the time drifts, its that cs1.6 servers will stop running when he correct the drift. All system have a drift of the time.
Looking at a strace of hldm, it does both gettimeofday() and adjtime(). So they read the system epoch time. gettimeofday, settimeofday -- get/set date and time adjtime -- correct the time to allow synchronization of the system clock I dont mind getting that kind of messages in the log saying time went backwards > 1s, its a good warning that the system is not super configured. But it should not stop the cs-server. Even if ntpdate is runned like once a say and the time is set 823 seconds backwards. For the other person that says that the time is set one hour with the daylight saving time. It will not be any different, since it is just cosmetics and the time is always the same, counting from 1970-01-01 00:00:00 GMT. And reading time will just get you the diff from that time to todays time. /Bjorn On Fri, 17 Jul 2009, Shane Arnold wrote: > You are missing the point.
