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?
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).
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.
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: (root) CMD (/Nessus/Targets/NessusScriptDataCenterScan.test) Mar 31 16:01:02 nes-001 CROND: (root) CMD (run-parts /etc/cron.hourly) Mar 31 16:01:02 nes-001 run-parts(/etc/cron.hourly): starting 0anacron Mar 31 16:01:02 nes-001 anacron: Anacron started on 2010-03-31 Mar 31 16:01:02 nes-001 anacron: Normal exit (0 jobs run) Mar 31 16:01:02 nes-001 run-parts(/etc/cron.hourly): 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.)
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).
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.
I am running GNOME on a slackware 10.1 sys. I want my desktop clock to sync itself with some remote time server...like in MS windows. If I cant do that, how do I manually reset the sys time so the desktop app will read the correct time?
Got a used Lenovo Thinkpad r61i and put Ubuntu 9.10 on it. Every time I turn it on it prompts me to give it a password for someone else's internet. This a password I do not know and I use an ethernet cable for internet so it's really annoying. Any way to make it stop?
I have a Dell OptiPlex GX1 (CPU: Pentium II, 500Mhz). It's very old, and a while ago I installed an old version of Ubuntu on it. While it is switched on and booted up, everything is fine, however the trouble is when it is switched off, or just in BIOS.
The BIOS clock appears to be running at about 60x speed (eg minutes like seconds, hours like minutes). This happens both when switched off and when observing the clock from the BIOS menu. I really don't know what to do about this, and it's causing alot of problems, I've even had it get to the point where the system clock reset itself and would not recognise the OS as valid.
I used gconf-editor to change the format of the date and time displayed on the panel (I wanted sort-able strings for pasting into a table of OpenOffice base, since base can not automatically insert the current timestamp value into a column with the create time of its table row).which is not the default formatting, and the gconf-editor dialog does not show a separate attribute for setting the format of the date separately from the time format. Where is the format string for the date portion of the current date and time value ?
I have a windows computer that has a virus on it. This computer isn't worth much so I don't want to get a virus program to clear it. I know the virus probably won't be able to crash the linux OS, but will it be able to transfer itself to flash drives if I am running linux?
I have been told by the staff from supermicro to update my BIOS, but they only have .exe to update. I ask them if they can help me to update my bios from Centos, and this is what they said
You can use RHEL driver: [URL] use same kernel driver for CentOS as RHEL. I'm really new with Centos OS, can you guide me on how would I be able to update my software via RHEL Driver? I see alot of RPM and images.
I am using a Dell dimension 4550 with pentium 4 processor. My current BOIS is A01. I am running Slackware 13. My current problem is that whenever I reboot, the keyboard fails just before the kernel selection page. This isn't a huge problem because I only have one kernel to boot but it is quite annoying. Whenever I shutdown the computer and boot it up again the keyboard works fine. The problem only occurs when I reboot.How do I fix this? Would updating the BIOS solve the problem?
I need to write a small application which needs to detect if the system time is changed by an another application/user and perform some action as soon as it is detected (maybe log the data that time has changed, along with info about which application/user changed it).
How can this be achieved?
I have good programming experiences in shell script, c and beginner level in python. I don't need to know when it was changed, just need to know who/what changed it. The system uses NTP to sync the time, but it is also possible for anyone/any application to change the time(for eg: using the simple "date" command as well).
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:
I have som packages installed from the Ubuntu repos that I don't want to be updated (if a new version comes) when I run "apt-get upgrade". How can I forbid aptupdate those packages, but update all of the others packages as normal?
Today i downloded latest ubuntu 10.4.1 and installed from windows environment (so you know am new with ubuntu) after installing i tried updating ubuntu, including some kernel updates, but after updating ubuntu not loading up, it just show the loading page that all nothing change i tried recovery mode but i dint understood anything it show some command prompt. i had used 10.4.0 before.
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?
I am following the instructions on Section 8.1.* Device Driver ConceptsHere I was able to proceed till section 8.1.4.After making the hello.c file,the make file and patching the Kconfig as mentioned,I tried to run the $ make ARCH=ARM CROSS_COMPILE=xscale_be- gconfig This gave error as:make: *** No rule to make target `gconfig'. Stop.I am not sure if my kernel is correctly compliled,but I was able to complie and build the kernel for arm before by cloning the kernel and building from the following link without any error. https://omapzoom.org/gf/project/omap...ux+OMAP+Kernel
I recently noticed that the time displayed in the Gnome Clock applet is exactly (or nearly so) one second behind NTP time.I have a NTP server on my small network to which I sync my other PCs. Some of the applications I run are critical of time and need sub second accuracy - I am also a bit of Time Nut as well.My NTP server is OK. My PCs can sync to my NTP server OK. My applications which require precise time get the right time from NTP - BUT - the time displayed in the GNOME Clock applet is always behind one second!I have spent much time searching for others with similar problems and their solutions but so far nothing - hence my asking here, why do I see this behaviour and what can I do about it
When I travel, I would like to tell my laptop that I, as a user, am in a different time zone that what the OS may think is local. And I would like the clock on my desktop (default Gnome bar date/time display) to show the local time.
Instead, I currently have to use sudo and change the system time... (click on the clock, choose time settings, set system time -- there are no other choices given). The applet thing allows me to add other locations, but they only show up if I click on the icon, as extra times below the main one.
I have been using clock() for calculating CPU time and time() for calculating Wall time. However, since time() does not provided milli / microsecond accurancy, I started using gettimeofday() as below to calculate wall time,
Certain times, I have been noticing that WALLTIME calculated is lesser than CPUTIME. I am not sure why ? Double checked the simple code, nothing seems to be wrong in simple subtraction. My understanding was always WALLTIME (elapsed time) remains higher than CPUTIME (compute time). I run my application on head node of a Linux cluster comprising of 24 compute nodes, each with 8 processors.
Trying to adjust my clock settings!I am running KDE 4.4.3 on Squeeze, on an 64bit laptop.(I used the AMD64 net install version)How can I fix the time settings so it shows 5:00pm instead of 17:00:00So far I have not been able to find a cure
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.
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.
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.
When I boot into Debian (lenny) my clock is always 4 hours slow. Whether I set it manually, or set it to get it's time from the network, the next time I boot into debian, it's back to being 4 hours slow.
