Ubuntu :: Conky Clock And Top Panel Clock Not In Sync

May 27, 2011

I'm using a very simple conky script to diplay the date and time on my desktop. I've noticed that he conky clock is a few seconds early compared to the time displayed in the right hand side of the top panel (Natty). I guess both displays are based on the same "internal" time, so I'm left wondering how this could happen, and how to sync back the clocks.

It seems that Conky is in sync with the system date, while the panel clock is 2 seconds late (on my system). Checked with while true; do date; sleep 0.1; done

CentOS 5 :: Get Rid Of Virtual Clock And Use Physical Clock?

Sep 2, 2011

I had cloned a centos 5.6 installation from virtualbox virtual machine to physical box. Everything work fine. However, the time showing in os using date command differs from bios time by roughly 4 hours. I am running ntp services which sync the time with another centos server on the network. It appears that some services are using virtual clock and some use physical clock. How do I get rid of virtual clock and only use physical clock?

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?

General :: How Does Windows Set It's Clock

Jun 30, 2011

Ubuntu :: Clock Isn't Showing Up?

Mar 8, 2011

I've finally returned to Ubuntu after leaving it in 2005 because of compatibility issues, but now I'm back and am hoping to stay. My experience with Ubuntu has been great by far and I can safely say that it has improved since '05. Anyway, I'm just wanting to fix this minor little occurrence I just had. You see, the Ubuntu clock and weather isn't appearing anymore. It was there and I don't even remember seeing it removed until now. I don't recall doing anything other than browse the web at the moment and I do recall the time being there before I did some surfing. Anyway, My name is still listed in the upper-right corner of the screen still. Just not the time. Did anyone else have this problem and know of a fix?

Fedora :: F13-14 Hangs And Clock Drifts

Nov 27, 2010

I've been running a fedora server for over a year now, and has seen some very strange issue, that really make it uncomfortable to use, and that I cannot manage to solve easily.

The problem is as follow : sometimes (every 20-30 minutes or so : this time is quite random), the server completely hangs.

I'm using it mainly remotely, through ssh and nfs. What I see when it "hangs" is the following:
-no ping response
-nfs stalled
-ssh sessions hangs (for example, if I run a "top" command", it just isn't updated anymore
-disk activity led stays completely off (in normal activity, it is almost always blinking, even due to "internal" server activities, so network disconnection doesn't explain that either)

The most strange thing is that, to resume it, I basically have 3 options : wait (sometimes few tens of seconds, usually between 2 and 4 minutes!), just hit a key on the keyboard!, or do something like un/plugging any king of usb peripheral (which makes me think of some interruption mechanism that is stalled).

When it "wakes up", I see my "top" session over ssh suddenly being quickly updated hundreds of times (for all it has not received during the "pause"), ping says that the packets have actually all been received (with long times, for example, packet 1 : 80xxxms, packet 2 : 79xxxms, packet 3 : 78xxxms..... packet 79 : 1xxxms, packet 80 : 0.xxxms), the disk is quite overloaded for a few seconds, and everything is back at normal!

Furthermore, I think this i related, but my clock drifts for few hours per day (3 holding minutes every 20-30 minutes makes me think there is some relation!)
I tried to set up ntpd to compensate it, but sometimes the suspensions are just too long, and I ended up with

Nov 27 01:22:36 server ntpd[699]: 0617 07 panic_stop +1203 s; set clock manually within 1000 s
and ntpd dies...

You'll ask me to have a look at the log, which I did by


But when the suspension happens, there is absolutely nothing new in all those files!

Version information :


I said in the title "F13-F14", because I already had the problem with F13, but after some time it disappeared (I may have changed some configuration, I have to admit...). I still have a backup of the "/etc" tree of that "working" F13.

The hardware for F13[working] and F14[not_working] is the same : Phenom II X4 on an ASUS M3N78 PRO, data on raid 10, system on separated SATA disk, 8Gb RAM, some qemu vms running (between 4 and 6).

OpenSUSE :: Clock On Panel Dissapeared

Aug 9, 2010

There is no clock on my panel after the 11.3 install. I don't get it. I unlock the widgets and there is a digital clock there, but I cannot drag it to the panel, only the desktop. So I suppose there is another way of adding it. The standard clock is not a widget?

General :: Clock Correction In GNU - Crontab?

Oct 20, 2010

My laptop's clock (Acer Extensa 5220) seems to be slow. I've corrected it 5 minutes forward last week and now have just corrected minute forward again. Is there a program [apart from time servers] to correct clock properly, for example, by shifting it a bit every hour? Is there already a program to put it to crontab or I should hack up a script? Or I should check more things?

I have found that HW clock is right, but system time is slow: about a second each 2.1 hours.
root@vi-notebook:~# dmesg | egrep 'clock|unstable'
[ 0.103785] Switching to clocksource tsc
[ 0.265274] Marking TSC unstable due to TSC halts in idle
[ 0.265514] Switching to clocksource acpi_pm
[ 1.321408] rtc_cmos 00:09: setting system clock to 2010-10-30 00:10:48 UTC (1288397448)
Is placing "hwlock --hctosys" to crontab a right thing?

General :: Set Windows To Use System Clock As UTC?

Jan 28, 2011

While dual-booting Windows and Linux, Linux sets the system time to UTC, so Windows thinks it's midnight near mid-morning. Is there any other way to tell Windows to use UTC? I've seen the registry tweak proposed here and other places. This does not work on my computer (Windows 7 32-bit).For reference, the registry entry is this:HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlTimeZoneInformation]"RealTimeIsUniversal"=dword:00000001

Ubuntu :: 10.04 Does Not Auto Clock Down CPU When Idle

Jul 7, 2010

When I'm on windows 7 my core i3 processors automatically clocks down when not much CPU power is needed. Somehow I have the idea that ubuntu 10.04 doesn't auto clock down my CPU when idle. I can tell by the short life my full battery has on ubuntu. Only 2hours compared to 5 on windows 7. Is there a way to manage this? So that the CPU automaticly adjusts it's clock settings?

Ubuntu :: Alarm Clock Program Goes Off?

Sep 24, 2010

I'm looking for an easy to use alarm clock program that I can suggest to new users. The two I have tried so far have fallen short of my expectations. "Alarm Clock" from the Ubuntu software repository starts out okay, but when the alarm actually goes off, getting it to stop seems pretty unintuitive. Click on the Alarm Clock icon, then click a Stop button in the new window that pops up. Sounds easy enough except that the icon used for "Stop" is just this grey square, so for users who are not familiar with linux or this program, it isn't even obvious that it is a button. I had one user actually uninstall the thing in order to get it to shut up. Preferably one should be able to silence the alarm by click on the alarm icon (or right clicking, if a 'doze' behavior is preferred) The other one I tried was alarm-clock-applet, which wants me to locate an alarm sound on my filesystem. Uh, no.

Does anyone know of a simple, basic alarm clock system that anyone can just sit down and immediately use without having to 'get in to the head' of the developer? Are the KDE alarms better? Am I missing something about either of these programs which would make them easier to use?

PS1: you have 7 minutes left to answer
