Software :: Why System Clock Runs Faster Than Hardware Time

Jan 23, 2011

My server is a VPS which is running with CentOS. I found a wield problem that the system clock always runs faster than the hardware clock. For example, I set system clock and hardware clock both on 20:00. After about half an hour, the system clock will be 20:34/5 which is wrong while the hardware clock remains correct (20:30).

Ubuntu Servers :: System Time Runs Slow Hareware Time Run Right?

Apr 11, 2011

I am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.

I can set it right by coping the hareware time to system time with this command:

Code:
hwclock --hctosys

I want to run a crontab to have that command run every minute. But it don't seem to run.

[Code]...

Ubuntu :: How To Make System Boot Faster By Removing Idle Time

Jun 14, 2011

How to make the system boot faster by removing the idle time between 5s to 10s? bootchart attached. It is Ubuntu10.04LTS by the way. One more hint, the screen black out for ~4s after "Begin: Running /scripts/init-bottom... Done." I don't know what is going on during that 4s, but my best guess is there is a way we can get rid of it.
Bootchart can be found here:

Ubuntu :: System Clock Will Not Set To Local Time

Aug 15, 2010

Try as I might I cannot seem to get the system clock to display local time. It looks like it's stuck on GMT. In the System>Administration>Time and Date I have my local time zone set correctly and also set to update automatically with an appropriate time server selected. It still displays my local time +5 hours (I'm central time, USA).

Ubuntu :: Plasma Clock Not Same As System Time

Feb 16, 2011

I restored my .kde directory after changing some stuff unrelated to my clock and now all plasma clocks are exactly 5 hours faster than my system time (the correct time).I've set the time zone for Date&Time in System Settings properly and that's working well and I've ALSO gone into the time zone settings for the plasma widgets and switched between UTC and Local manually but that doesn't do anything.

Software :: Cron Clock Is An Hour Off To System Time

Mar 31, 2010

I have cron jobs running and the timing is critical, because I'm running Nessus scans on production servers. If I hit them at the wrong time, I'm toast. But when I check the cron log, I see that it is an hour off. Here is the output for the command "clock":
Wed 31 Mar 2010 03:01:26 PM CDT -0.257677 seconds

And this is the tail of the cron log:
Mar 31 16:00:01 nes-001 CROND[8790]: (root) CMD (/Nessus/Targets/NessusScriptDataCenterScan.test)
Mar 31 16:01:02 nes-001 CROND[8822]: (root) CMD (run-parts /etc/cron.hourly)
Mar 31 16:01:02 nes-001 run-parts(/etc/cron.hourly)[8822]: starting 0anacron
Mar 31 16:01:02 nes-001 anacron[8832]: Anacron started on 2010-03-31
Mar 31 16:01:02 nes-001 anacron[8832]: Normal exit (0 jobs run)
Mar 31 16:01:02 nes-001 run-parts(/etc/cron.hourly)[8834]: finished 0anacron

Cron thinks it is 4:00 p.m., but it's really 3:00 p.m. How do I tell Cron what time it is? (Stopping and restarting the crond service did not change it.)

Software :: Hardware Clock Differs From System Time After Setting

Feb 26, 2009

I'm setting the hardware clock on RHEL 5.1 system using /sbin/hwclock --systohc. After setting the clock I issue a date command followed by a /sbin/hwclock --show from within a script to get fast resolution and I see that the hardware clock precedes the system time on average by .5 seconds. I would think the clock should be identical after setting.

Ubuntu :: Need To Make System Stop Updating BIOS Clock To UTC Time

Jan 22, 2011

I have Ubuntu 10.04.1 32bit installed on my flash drive so wherever I go I can have my own mini personal computer, but one problem I'm having is every computer it is run on the next time it's rebooted to the OS on the hard drive it has UTC time instead of the actual time for the timezone you're in that Windows uses. So is their a way I can make Ubuntu not automatically change the clock to what it wants?

Ubuntu :: Put Frequently Used Programs In Ram For Faster Startup Time?

Jun 12, 2010

I was wondering if there is any tool or program that stores a copy of frequently used files eg. Binarys, program library's etc. in memory so when they are requested by the OS they load instantly. I'm asking because I have a system with plenty of ram but very slow hard disks. Having programs like opera and java/eclipse load from ram would greatly speed up their start time. Ideally they would be loaded into ram in the background after I log in. Of course all writes made to these files would have to be made to the files on disk for obvious reasons.I don't want the entire OS in ram because it will not fit, just frequently accessed files.

I installed Fedora 15 yesterday. Took a few hours to get used to the Gnome 3 interface, and I love it.I noticed that my fan seems to be running all the time irrespective of system load, even when it's idle.An internet search yielded this supposedly resolved issue where the fan ran constantly on systems with Intel integrated graphicsLike that link states, I am running the latest updatedl kernel-2.6.38.6-27.fc15, but the fan running continuously issue still persists.

CentOS 5 :: Cron Job Runs At Incorrect Time - Clocks Seem Ok

Mar 9, 2010

Within a VMWare ESX virtual machine, I am running CentOS 5.2. (Actually, it is kind of a virtual appliance to run CollabNet's Teamforge - which I have installed for a trial). I've been dabling with Linux for a year or so, but I know I have much to learn.

I'm attempting to run a cron job that runs a backup script at 11pm. It works great, but unfortunately it runs at 11:30 am.

I created the cron job using 'crontab -e', while logged in as root. My cron job line is : 0 23 * * 1,2,3,4,5 /etc/tjt_backup/collabnet_backup.sh

If I type 'date', I get the correct date/time in my timezone: Tue Mar 9 16:27:12 CST 2010

If I type 'clock', I also get the correct date/time: Tue 09 Mar 2010 04:26:57 PM CST -0.463330 seconds

(Although, it appears there is a little drift)

Fedora :: Cannot Set Time Of Clock

Jul 29, 2009

When installing I perhaps mistakingly told Fedora it should use the BIOS clock and now it shows the wrong time, 1 hour ahead of my time-zone GMT+0. If I try and go to the preferences and set the time the 'Advanced Options' one of which I need are grayed out, I need the 'Use local time source' option to be unchecked. Could somebody tell me a workaround or the command-line commands to tell it not to do this anymore?

Fedora :: Clock - Can't Get Accurate Time On Systems

Jul 7, 2009

I have dual boot on my comp. Windows XP and Fedora 11 Now in both systems time zone is set to Belgrade ( which is my time zone), but when I setup clock in fedora to be, let's say 16.15h, then when I swich to windows it says time is 14.15h. When I setup in windows on 16.15h, and I swich to fedora, it says time is 18.15h. So I can't get accurate time on both systems in no way.

Fedora :: Show Clock To Civilian Time?

Nov 12, 2009

By default, Fedora 11 sets my clock to military time. For example it says 16:22. I would like it to show civilian time (or at least know how to do it) I logged into the clock settings and had to put in the root password, but couldn't find where you do this. If you scroll on the time for hours, it just goes from 0 to 23 and back, not to AM and PM like some others.

OpenSUSE :: Time / Clock Resets - Random On 11.3

Sep 3, 2010

I done searches for "clock" and found similar threads, but no real fix that is working for me. My clock resets when I boot into linux. It does not happen in windows or bios even on cold boots. The battery is replaced and good** the old battery was by all measures dead (0.6v), but still seemed to have enough power for the clock, since windows tested fine with it.

I have tryed setting it to local time, UTC.. etc... My timezone is GMT (london). "sudo /sbin/hwclock --systohc" Although I have windows, I do not use it except the few times to test this, so no conflict.

Fedora :: Clock - Boot Into To 12 Time Is Wrong But Not In Windows

Oct 29, 2009

I'm running windows 7 and the F12 Beta (although the same issue existed in my f11 distro) on an asus g71 bb. When ever I boot into windows my time is correct. If I boot into to F12 my time is wrong. Usually by 4 hours. If I change it in Linux when I boot into windows I end up switching the time on my windows partition. I tried searching the forum (rather casual I'll admit) and couldn't find any solutions.

OpenSUSE Install :: Clock Not Showing Correctly The Time

Jan 12, 2010

I have this problem for a while but didn't notice it until lately(i did reboot the machine for few months). Now that i reboot it frequently i notice that the clock is always not what is supposed to be. I'm in Toronto, Canada so it should be GMT -5:00. Sometimes it shows GMT-6, sometimes -10, now is GMT -11. Anyone would know why i have this issue? I'm running Suse11.1 on a 64 bit. My laptop which runs on 32 bit is working fine.(well probably different versions for kernel and kde.(whatever was in th repository to be updated i updated)
