Re: [gentoo-user] Losing time somewhere
Thank you the the hwclock tip it will solve my problem exactly. Unfortunatly it seems my problems were deeper and beyond the scope of this thread really, the loss of time was due to something within the kernel that I built last week I also realised that my hard disk performance had fallen dramatically, again due to some option selected or not within the .config. After a 6 hour session of tweaking last night, I decided to take the honourable way out and deleted the 2.6.12-r9 kernel and reverted to a 2.6.11.5 that came from a genkernel setup some time ago that has served me well for the last few months. Thanks for help on time issue, some reading to be done I think stu On 8/30/05, Uwe Thiem [EMAIL PROTECTED] wrote: On 30 August 2005 15:17, Stuart Howard wrote: thanks for the response So far as I can tell I have not had ntp on my system, I have not put it on myself the only way it could have been on is if it were a default during original install of Gentoo in which case --depclean ought not to have removed it as it should belong to something [world , system ] I may give up on chrony and put a ntp on and see if that cures it, though I prefer not to just mask a problem if there is one, could a clock slowdown be something as serious as an indication of hardware problems? Not really since your clock is on time after a boot. Please understand that there are two clocks involved. One is a hardware clock.

[gentoo-user] Losing time somewhere
Hi I am losing up to 10 minites a day on my system clock ie. if it is correct at boot then the following day, date will reply with a time that has lost up to 10 minites. Points that may be relavent, - The system has worked correctly for many months prior to next point. - This problem has occured since building a new kernel and changing to KDE as the desktop - Upon a reboot the time has corrected itself. My questions are - The kernel was the first I have done without genkernel or oldconfig is there an option that could be casuing this? - Can KDE be causing this? though if I drop out of KDE date still outputs the incorrect time. - I tried to install chrony to adjust the time, though it seems to be working ie. from logs, though it does not update the sytstem time, could there be a permissions issue somewhere or have I lost something that checks or sync's the system time? - As I wrote last question I realised that I did my first emerge -av --depclean a few days ago is it possible that I have removed some app that keeps a check on system time? OK, well thanks for reading this far, above are the points that I have manged to scrape up but do not know how to answer are there any other points that may be affecting this any suggestions at all ? regards stu -- There are 10 types of people in this world: those who understand binary, those who don't --Unknown -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] Losing time somewhere
thanks for the response So far as I can tell I have not had ntp on my system, I have not put it on myself the only way it could have been on is if it were a default during original install of Gentoo in which case --depclean ought not to have removed it as it should belong to something [world , system ] I may give up on chrony and put a ntp on and see if that cures it, though I prefer not to just mask a problem if there is one, could a clock slowdown be something as serious as an indication of hardware problems? stu On 8/30/05, A.

Re: [gentoo-user] Losing time somewhere
ntp of any flavor does not seem to be in the default install, i had to emerge it on all my boxes. I'm from an ibm rs/6000 aix background, so I learned long ago to NEVER trust the system clock. rs/6000 boxes tend to have very poor hardware clocks for some reasonprobably because you never pay that much for a server not connected to something :) On Tuesday 30 August 2005 09:17, Stuart Howard wrote: thanks for the response So far as I can tell I have not had ntp on my system, I have not put it on myself the only way it could have been on is if it were a default during original install of Gentoo in which case --depclean ought not to have removed it as it should belong to something [world , system ] I may give up on chrony and put a ntp on and see if that cures it, though I prefer not to just mask a problem if there is one, could a clock slowdown be something as serious as an indication of hardware problems? stu On 8/30/05, A.
