I want to know the time on a server accurate to the millisecond.there's this way:
local $ ssh user@servername
Welcome to server!
server $ date
Fri Feb 18 11:27:50 EST 2011
But I need more accuracy. Is there a command that will be more precise?
Is there a way to get the current time as provided from NTP (not the currently set time on the server)?

Sometimes it is possible to trick a Linux app by calling it like this:
HOME=/tmp/foo myapp
This would make myapp think /tmp/foo is the home directory, it won't try to get the user id, find its home directory via getpwent(). This is useful when myapp must be forced to dump some of its config files into a non-standard location different than ~.
A similar trick can be done like this: LANG=foo LC_ALL=bar myapp
This is useful when myapp needs to be called once with a different locale without having to make the change persistent by using the export bash built-in or even modify stuff in /etc/profile.
Is it possible to pull the same trick with time and date? The goal is to make an app use another time than the system ones. The final goal - to make timestamps that appear in logs/commit messages not being tied to the system time.
I am reading about jiffies in linux kernel. In one of the related example in the book Linux Device Driver, the author use
head -8 /proc/currentime
to print out some time information.
However this file is not present in my linux installation (kernel: 2.6.32-131.6.1.el6.x86_64). Why is it the case? Is it because the file path is no longer valid, or it is a distribution feature thing? It is not present in OSX too. What would be an equivalent in OSX?
I want to run a script that runs after every 15 minutes that i will do using crontab. But in script want to search a string from the last 15 minutes logs in log file containing data of whole day.
how i can search the string according to time difference that is logs from from current time and current time - 15 minutes.
Sample logs are as follows:

View 1 Replies View RelatedI am using the Terminal. I would like to know how do I put the current date and time on my machine and the date from a certain URL that has .php extension into a file.
After much too often wondering "hey, when did I actually start this time-consuming command?", I'm considering adding a timestamp to my bash prompt.My first try was simple: PS1="(A) $PS1" which gives a display like:(16:58) exscape ~ #
However, the problem with that approach is that it displays the time when the line was written, not when the command on it was executed. So, if I run "ls" at 16:58, and get a new prompt "(16:58) ..." and then run the next command 2 hours later, it'll look like this:(16:58) exscape ~ # new-commandI of course want the line to display the time when the command was actually run, not when the prompt appeared.

I'm looking for a function (prefer POSIX, but Linux specific would do if it has to) to get the current timezone offset. For my location, eastern USA, that should be -14400 when daylight time is in effect, and -18000 otherwise.
View 1 Replies View RelatedI'm trying to copy files from my current server to a new server. Both servers have SSH installed. These are the commands I'm using. However I'm getting connection refused. I did a google search and found out that maybe the reason of this error could be due to the fact that my current server doesn't have SSH. However I use SSH often on my current server so I can say that it has SSH for sure.

View 4 Replies View RelatedI am running Slackware64-current(multi-lib) and I have stumbled across something that I don't fully understand.I have read that the kernel-headers should not be updated as glibc is compiled against them and therefore requires that set of kernel headers. Recently the kernel version has been bumped a couple of times but glibc has stayed the same.Should glibc be re-compiled each time there is a kernel update?
Perhaps someone can explain, in very simple terms, the relationship between the kernel, the kernel headers, the kernel modules and glibc.
Got an Asus eeepc 900a. Runs Intel 915 graphics. Upgraded to slackware current last week. X would not start. Based on info here, I reverted back to earlier libdrm and xf86-video-intel. That got it working again.
Updated Slackware current again today. I think I got a new kernel. Now, halfway through boot time, the screen goes blank, then comes back and the font is tiny. Gone into framebuffer mode. If I start X, it just freezes. Nothing but a reboot will get out of it.
I have vga=normal in lilo.conf, but I read that this is no longer used. I can find no way to turn off framebuffer mode. From other threads here, I have tried append="i915.modeset=1" in lilo.conf. Has no effect.
I could revert Slackware to 13.0 from current, and that would make the eeepc useful again. Is there anything else I should try?
I have several file servers in our offices and I am relatively new to Ubuntu / Linux. I get notices that there are updates for the server software from time to time. Is it typical to update everything when available or should I follow "If it ain't broke, don't fix it..." mentality?I would hate for everything to be working fine and then have an update throw me a curve.

I recently set up a kickstart server using Centos 5. I copied all 7 of the centos 5 install cd's to the tree. I made the install cd, it boots fine. I'm using http, when I'm prompted, I put in the web site: 1.1.1.1 and the Centos directory of /network-install/RPM

I am hosting two Virtual Servers both running Centos 5.3 on a host machine also running the same OS. The VM software in use is Xen, as supplied with the OS.The host machine's time and date is fine, however both Virtual Servers are running ahead of real time consitantly.Running /etc/init.d/ntpd restart will resolve the issue however one of these is running MailScanner and when the time suddenly goes backwards, sometimes by as much as an hour, it stops working properly.
View 1 Replies View RelatedI have a set of machines on a disconnected network. Periodically, one of the machines connects to the internet and synchronizes its time with a time server that is not known until the connection is established. (The machine queries a central command server for the address of the time server it should synchronize to.)
I then use a custom tool to do some calculations to call adjtimex() and adjust the clock so that it runs fairly accurately.
I know ntpd is supposed to be able to handle disconnected networks but I thought you had to preconfigure the servers in the configuration file.
My intent is to run ntpd on this machine (without configured "server"s) so that it can serve time to the internal network. (Periodic synchronization using ntpdate from the internal machine to the bridge machine.)
The problem: ntpd wants to fuss with the values I set using adjtimex(). I want it to quit thinking it needs to adjust the clock and just serve time to the internal network. (Maybe I have a GPS time source hooked directly to the machine!)
