Background
I want to monitor a running linux system over several days. It's a custom gentoo build and with much custom software on board. This software has ongoing maintenance timers and cron scripts and other clock driven events. I need to verify these scheduled events are working.
Problem
Waiting for the system to step through daily and…
Hi,
I know that constant switching time of the Linux scheduler was a big achievement.
I was just asking myself the question what would be the implication of a non-constant
switching time. The only obvious reason I can think of is real-time systems where we have to meet deadlines. There it is obviously no ideal if the switching time is…
My web app runs on windows 2003 .Net 3.5
I have users from Israel (GMT +2), and Israel switched to Daylight saving time on 26/3/10 so now it's (GMT +3).
I use TimeZoneInfo.ConvertTime that doesn’t know the Daylight saving time switch is on 26/3/10 so it still converts to GMT +2.
I asked on StackOverflow:…
We have a small project we are working on part-time that runs on Nginx/MongoDB on Ubuntu 10.04 LTS Server. We'd like to be able to see reports on things like server load, requests/sec, response time, DB load, DB response time, etc. Is there an open source or free (as in beer) tool that can parse such logs…
I have a Windows VM that has time drift problems, and left to its own devices will drift by minutes per day.
I know there are issues with time on VMs, but I was hoping using the Meinberg NTP service would be successful.
It works, generally, in that the time gets corrected in one big step about once…
I see a warning in my Win7 Events Log:
The time service has not synchronized the system time for 86400 seconds because none of the time service providers provided a usable time stamp.
The message suggests that I run:
w32tm /resync
When I try to run that command, I get an error:
The following…
I'm using Wireshark to time tag and get some statistics on multicast traffic. When there is not much traffic, the stats looks good, but as soon as there is a bunch of packets arriving at the same time, I have stats that are not even possible (e.g. round trip time of 0ms)
I'm wondering if Netmon…
I'm having some problems with synchronization with an NTP server.
1) The NTP daemon doesn't sync the system clock at all, even though it's running (confirmed with /etc/init.d/ntp status).
Forcing to sync with ntpd -q or ntpd -gq does not work either.
2) Stopping the NTP daemon and syncing…
I have a script that I want to have an if statement check if a file falls between several specified date periods as it searches directories. I have been able to get the time in %Y-%m-%d format for the file, but I can't seem to be able to specify a date range for python to go through. Any…
We currently have setting to sync time when spread is more than 5 mins, but it's getting to a point where some applications don't accept it. What is best practice out there to sync time for all windows and unix boxes to sync with time server or domain controller.
Windows time service is…
I am trying to recreate a problem I encountered to try to confirm the root causes of it. One of the possible theory is that the problem is being caused because the server hadn't restarted for along time. Since I've already restarted the computer, Is there a way of resetting/modifying the…
I have implemented basic shadow mapping for the first time in OpenGL using shaders and I'm facing some problems. Below you can see an example of my rendered scene:
The process of the shadow mapping I'm following is that I render the scene to the framebuffer using a View…
I'm working on building out a 2.5D engine and having massive problems getting my shadows working. I'm at a point where I'm VERY close.
So, let's see a picture to see what I have:
As you can see above, the image has lighting -- but the shadow map is displaying…
Yes, it's now only two weeks to the start of the 17th JavaOne conference!
This will be my ninth JavaOne, I came fairly late to this event, attending for the first time in 2002. Since then I've missed two conferences, 2006 for the birth of my son (a…
I am hoping to make this question and the answers to it the definitive guide to dealing with daylight saving time, in particular for dealing with the actual change overs.
If you have anything to add, please do

Hello, and first off thanks for your time to look at this.
For a research project I'm working on, I have a somewhat complex design (which I've been given) to persist to a database via NHibernate.
Here's an…
In this series, I will be taking sample applications from the iPhone SDK and implementing them on Windows Phone 7 Series. My goal is to do as much of an apples-to-apples comparison as I can. This…
Hey,
I would like to write a code involving automatic selection of a best composite model using ETS as well as autoregressive models. What is the criteria I should base my selection on?
Also if I'm using…

I'm running Arch Linux. Recently, when I turn on my PC, the system time is set to 1:00 1 January 1970 - presumably the 1:00 o'clock is from the timezone shift.
Does anyone have any ideas why systemd…
