Ubuntu :: Adjust The Clocks Of Two Laptops To Same Time In HH:MM:SS Using Date Function?
Feb 12, 2011
We are doing a project related to clock synchronisation. We have two laptops: Compaq and IBM Thinkpad. If we adjust the clocks of two laptops to same time in HH:MM:SS using datefunction, in about half an hour, both the clock drift by about 10-15 min We are wondering how this is possible???We have compiled kernel 2.6.36.2 on both laptops and set the value of HZ to 1000. Then what is the reason for such a significant drift in short interval of time??Is this related to crystal oscillator or anything else?

If one right-clicks on the date and time tab in Ubuntu 10.10 desktop, then there is no obvious way to change the time. If one right-clicks and goes to help, then the explanation for changing time is as follows under the category 'usage':
2.3. To Adjust the System Date or Time.
To adjust the system date or time that the Clock applet displays, perform the following steps:
1. Right-click on the applet, then choose Adjust Date & Time.
2. Type the root password, then click OK.
3. The Clock applet starts the system tool that sets the system date and time. Use the tool to adjust the date and time.
The actual way to do this is as follows:
Right-click on the date and time applet. select preferences, and down at the bottom of the window that opens push the 'time settings' button.
Then you will be able to adjust that date and time.

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)

I've got fedora 11 set up to use network time protocol to sync my laptop's date & time when I'm on-line. The question is simple really, I've added a local universality's time server (what is public) and it's live. but it's added to the end of the default time servers what come with fedora. How do I get fedora to just use the local time server, is it a case of removing the default time servers for fedora, but there is a box what says advanced options which are. sync system clock before starting service ???? & use Local time source (( is that the same as the local ntp server that I've got set up ))Hope some body can help me with the network time protocol part of Date/Time settings.

I am using Debian linux. I have 100 timers running. If a timer expired which will generate a signal and it was mapped to a same function handler. All the timers are mapped to one function handler. The problem is if the timer expires one at a time, the function handler called at a time. But if the 2 timers expires at a time, the function handler is called one time only instead 2 times. Is it possible to invoke the function handler as many times based on timer expirary happens simultaneoulsy?

how do you adjust the response time of the taskbar menus, such as when you click on the start button on the bottom left of the desktop? My problem is that when I click them, it would delay for about 1 second before popping up the menu. But right-clicking on the desktop popped out fine without any delay though. Is this normal? Where do I adjust the settings for this? I have configured my ATI graphics card succesfully. Direct rendering, desktop animation and everything else is working fine btw.

where the time to display media notifications is stored? When I put a CD or DVD into the player slot, a popup window shows possible actions to take but these old eyes can't read it fast enough to get through the list. Is it possible to get it to display longer and if so how?
When I put an audio CD in the slot, the display says there are six (6) actions possible but I only have time enough to read the first 2 or 3.

I've noticed that every time this desktop is turned on the date & time are as they were the last time I used it, and then have to put in the correct date & time again (this is why I chose the word 'persistent' within the tittle). When I try to change those have to write in the password for the date as well as for the time as if 'login-in' once were not enough! What I want to know is how to put in the date & time and receive the correct amounts the next time I turn the unit on again, as it should be? Do I've to open a terminal & do it with administrator's authority/credentials?

ubuntu 10.10 64bit my system clock keeps running late, and for some reason, I can't use NTP to synchronize it.If I try to use System -> Preferences -> Administration -> Time and date I can't unlock the popup (see attached screenshot) - I can click on the little yellow lock icon but when I do so, nothing happens.I tried "sudo ntpdate..." but i get the "the NTP socket is in use, exiting" error.

Since my clean install of 11.04 using the Unity desktop (takes a little getting used to) I notice I cannot adjust the system clock any more...
I usually configure Ubuntu to sync to an internet time server but this is no longer possible as I cannot open the System Settings > Time and Date dialog.

Lucid 10.04, auto upgraded from 9.10, accessed through NoMachine NX from my MacBook Pro 10.6 system.
When I try to access the time settings through the System > Administration > Time and Date menu, all I get is the greyed-out display with the message Not authotized to make changes at the bottom.
With other administration functions, I am asked for sudo-style authorization with my password. That doesn't happen with Time and Date.

Just bought a refurb PC900 and also now have a SDHC Flash with Ubuntu 10.4 netbook remix on it so that I can boot from it. I am having a problem that the UNR shows the time and date 5 hours behind the real time. The notebook BIOS is correct. When I try to set the time and date it goes back to the original time that was set before withing a few seconds. I set up a new user with administrator full access but that did not solve the issue. I have also tried setting up Ubunto One but my system does not act like the directions online. Can I get files from my non-ubunto pc to my PC900? It seems only one way to me right now.

I'm using ubuntu Maverick on a Dell 1545 and I'm pretty much a newbie to ubuntu. Most of the things have been fine so far, I just plugged it into a proxyless internet connection and adjusted my location for time zone (I've been using a porxy server previously for internet which didn't allow changes in location and time zone work) and since then that calendar has moved out of the scope on the top right corner of my screen and I'm unable to move it.

I'm trying to change the time stamps on a bunch of pictures in the same directory, because several cameras were used, some of them with the wrong time zone.exiftool seems to be the correct package to use, but it doesn't seem to work.
The following command seems to be the recommended way to subtract 1 hour from all .JPG files in the directory, but the exif data in the file and even the time stamps don't change.
Code:
exiftool -a -AllDates -=01:00 .

I recently installed Ubuntu 10.04 and am very happy with it. However I have this problem with the Gnome panel which does not keep the date and time up to date. I can see that the system has the right date and time but it seems to get stuck on the Gnome panel. I have researched, ntp, ntpd, ntpupdate, tried all the tricks. Not sure what to do next.

My date and time is not syncing correctly. I have 2 opensuse 11.1 servers and on both when you adjust the time in yast, I go back into yast and the setting for the NTP server is not set and "manual" is checked. I tried many times and the setting keeps reverting back. I always click on Save NTP configuration.
