I want to know how the computer sets time? When I turn off my computer or it is not connected to internet it shows me the correct time. When I login to my computer after so many days, it shows me the correct time though it was turned off for so many days. How is it possible?

I am a programmer working on embedded linux, On my device, I need to set time everytime when I want to use it to check my program.
Is there any command or script which sets time from some Internet timeserver everytime?
I am trying to set time using settimeofday in linux. But it sets local time. i.e works like SetLocalTime in windows. But I want to set system time(like SetSystemTime in windows). I could'nt find no other api in linux. What should i do? I had tried with mktime/gmtime apis
View 3 Replies View RelatedDuring Slackware 13.1 setup, I chose the hostname stella-sl2. This hostname is also the one that the system is displaying before I configured network access. After configuring wired network access to my Apple Time Capsule, my hostname suddenly changed to INTERFACE='eth0'. As a result I'm noticing some very strange things, like the login prompt which has become "INTERFACE='eth0' login: ".
After configuring wireless network access to the Time Capsule, the hostname changed to "INTERFACE='wlan0'". Note that, during boot, wlan0 is brought up AFTER eth0.
Also strange is this:
bash-4.1$ cat /etc/HOSTNAME
INTERFACE='eth0'.DNSSERVERS='10.0.1.1'
bash-4.1$ /bin/hostname
INTERFACE='wlan0'
bash-4.1$
Until now, it was only a minor annoyance, it didn't prevent anything from happening, internet connection was not affected. But now I'm configuring sendmail which needs to talk to a relay SMTP server, and sendmail "HELO"'s itself using the bogus hostname:
>>> HELO INTERFACE='wlan0'
<<< 501 HELO requires valid address
554 5.0.0 Service unavailable
Probably this is caused by the Time Capsule not adhering to standards. However, the Time Capsule's firmware is the latest version, so I cannot fix this. Is there a way to prevent dhcp from changing the hostname? How can I make sure that the hostname that I configured during setup remains active?

This is not what I'm looking for. Rather, I just want some insight into how I spend my time on my computer. I'd like to waste less time on my computer, and spend my time on more productive tasks. The first step to improving anything is to measure it. But I can't be bothered or remember to click on some icon and switch "projects" every time I change from my terminal to browsing ....., or something like that. I want the time I spend on different applications tracked automatically.

View 7 Replies View RelatedBasically, About 50% of the time, the system boots and sets the console resolution to something strange, and the console renders in a small box in the top-left hand corner of my screen. This causes problems not only with the display of the console, but with the display of X as well.
I have an Intel GL40 chipset on this laptop, with an integrated GMA4500 GPU. I am using the latest stable Intel video drivers (2.10.0-1), and have tried using the git drivers. In addition, the problem has been occuring since December, when I install Arch linux on this machine, I have just now had the time to address it. So basically, the issue has persisted with all driver versions since mid-December to the latest releases.
In addition, I have tried using several kernels, including:
But the problem persists with each.
I wish I could give you relevant diagnostic information for this issue, but if I had any idea where to start...
I will gladly post any information necessary. I was going to post a copy of everything.log for a successful and unsuccesful boot, but unfortunately they put me over the posing limit by about 100,000 characters each.
I guess, on second thought, that my Intel video driver really wouldn't have anything to do with my console, now would they?
I've installed 2 different distros on this old dell laptop, install goes fine, i run everything...reboot a few times. perfect, but the next day, when i boot up, i get " date/time" not set, if i choose to ignore that...computer won't boot... is this a battery issue ? the battery wont hold a charge, so i only run it with power pack...works great, but when i turn this on tomorrow, I'll get that w=error messy.
View 4 Replies View RelatedI was using openSUSE, then went to Mint. Before I had to tinker with all sorts of settings, and things to get wireless internet to work. Ubuntu just detected what drivers I needed & its simply got my wireless to work all on its' own.
Is 11.3 similar? I want to move back to openSUSE, but I don't want to tinker with this. I want to use my time on the computer for more productive things.
I've been thinking about setting up roaming profiles so that I can access my profile and settings from any computer in the house that has ubuntu booting on it. One thing that concerns me is, what happens if I log in using my profile from more than one computer at the same time? A couple examples:
1. I'm working on something on one pc, and go downstairs. A little while later I fire up a laptop down there and want to browse the web. What would happen?
2. I am logged in to my desktop, but let it go to standby. I later log on to a different pc on the network and load the same profile that was logged in (but in standby). What happens to the state of the profile when the desktop wakes up again?
Is in Ubuntu option, that can shutdown computer after time or at defined time? I think: I have turned on my computer and I will need to automatically shutdown computer after 4 hours or at 21.00 pm. Is there option, if computer can automatically turn on at defined time?
View 9 Replies View RelatedWhen I start the computer I receive the message that the drive that contains the /home partition has an error. If I press "F" the screen says that the drive is no ready, that I can wait, cancel or manually recovery. If I wait, in about 1 minute, the system starts normally. If I press "M" to repair manually, then I press fsck to repair the disk and apparently repairs the disk. But everytime I start (power on) the computer, Ubuntu always checks the disk and gives a dialog where I can: press F to attempt to fix the errors, I to ignore, S to skip mounting or M for manual recovery

But Once in a while (sometimes almost every time I start) the BIOS settings are reset and I have to disable floppy disk seek and reorder boot device list again. I have checked the battery and it's fine. What else can be the problem?

View 6 Replies View RelatedI am using Grub4Dos to boot Ubuntu 9.10 Desktop Live CD. In the menu.lst i made the following changes.
Quote:
title Ubuntu LiveCD 9.10
find --set-root /ubuntu-9.10-desktop-i386.iso
map /ubuntu-9.10-desktop-i386.iso (0xff)
map --hook
root (0xff)
[Code]....
The code runs fine and Ubuntu loads also from the ISO stored in the C: drive of my system.
The problem is when Ubuntu loads it changes my clock time. I have set the timezone to Indian Standard Time. Since it is live CD it should not make any changes in the system however, it does change the Data/Time of my system.
I have looked high and low for this, but to no avail. I am looking for a script to shutdown my computer when it reaches a specific time (say 10:00). I know about the shutdown command but if I use that I cannot shutdown my computer manually. I would like to be able to shutdown manually AND automatically.
