System time 12:05:00 string datetime = "12:15:00";
12:12:00 3 minutes ago MessageBox.Show ("3 minutes left");. How can i do it please give me a suggestion.
How can I update the Windows system clock time.windows.com I want to update the Windows time, but I know I can manually set the date time, but I do not know how to do it from the form
if you have a suggestion please share with me
As far as I can tell, you can't directly access the CMOS RTC clock under Windows via C#/.NET. In any case, from what I've read, doing so is likely to introduce other problems.
Instead, you might consider programmatically triggering Windows Internet Time to sync immediately, instead of having it wait up to a week for Windows to do it.
Another link for doing this
...and another one
...and yet another one (may be less helpful)
finally, here's a Code Project that seems to do something similar to what you want

I have a problem that If a person clock is not set correctly the app will take this time rather than the correct one that's why I wanted to take the time now form the internet. any idea ?
Note: I have used DateTime.now() and it provide back the mobile time not the real time
I am currently working on a code where I want to implement something like this:
if current_time is more that 12_am:
hello = "world"
Basically I want to set or change a variable if the current time in my computer is more than 12 am.
I did some research on datetime, however I could not find a function that does as told above.
If there is already an answer to this, please do redirect me and excuse my clumsiness.
The script needs to be running consantly.
You can set the check to True and then maybe break the while loop. All depeneds on your application.
import time
while True:
if int(time.strftime("%H")) > 12:
check = True
Let's say you are writing a program for Raspberry and you control some lights and you turn them on only after a certain time. On microcontrollers the programs always run endlessly.
You need to constantly run your script and check whether date is more than 12 am.
Another aproach would be to check how much time left and sleep for that long.
Hi I need to know how can I get current time in blackberry if I change the device time
I am using system.getcurrenttimemillis() method
Is it possible ???
Or concept of network time comes into this
System.currentTimeMillis gives you a timestamp in UTC, which is roughly the time in the Greenwich Meridian.
If your time is updated via network or changed in settings then the returned value changes as well.
I am writing a script to capture disk usage on a system (yes, I know there is software that can do this). For database reporting purposes, I want the interval between data points to be as equal as possible. For example, if I am polling disk usage every 10 minutes, I want every data point to be YYYY-MM-DD HH:[0-5]0:00. If I'm am polling every 5 minutes, it would be YYYY-MM-DD HH:[0-5][05]:00.
If I have a ksh script (or even a Perl script) to capture the disk usage, how can I let the script come active and wait for the next "Poll time" before taking a snapshot, and then sleep for the correct number of seconds until the next "Poll time". If I am polling every 5 minutes, and it is 11:42:00, then I want to sleep for 180 seconds so it will take a snapshot at 11:45:00 - and then sleep for 5 minutes so it will take another snapshot at 11:50:00.
I wrote a way that works if my poll time is every 10 minutes, but if I change the poll time to a different number, it doesn't work. I would like it to be flexible on the poll time.
I prefer to do this in shell script, but if it is way too much code, Perl would be fine too.
Any ideas on how to accomplish this?
Thanks in advance!

EDIT: Wow - I left out a pretty important part - that cron is disabled, so I will not be able to use cron for this task. I am very sorry to all the people who gave that as an answer, because yes, that is the perfect way to do what I wanted, if I could use cron.
I will be using our scheduler to kick off my script right before midnight every day, and I want the script to handle running at the exact "poll times", sleeping in between, and exiting at midnight.
Again, I'm very sorry for not clarifying on crontabs.
cron will do the job.
http://en.wikipedia.org/wiki/Cron
Just configure it to run your ksh script at the times you need and you are done
You might want to consider using cron. This is exactly what it was made for.
If I were doing this, I would use the system scheduler (cron or something else) to schedule my program to run every 180 seconds.
EDIT: I might have misunderstood your request. Are you looking more for something along the following lines? (I suspect there is a bug or two here):
ANOTHER EDIT: Remove dependency on Time::Local (but now I suspect more bugs ;-)
#!/usr/bin/perl
use strict;
use warnings;
use POSIX qw( strftime );
my $mins = 5;
while ( 1 ) {
my ($this_sec, $this_min) = (localtime)[0 .. 1];
my $next_min = $mins * ( 1 + int( $this_min / $mins ) );
my $to_sleep = 60 * int( $next_min - $this_min - 1 )
+ 60 - $this_sec;
warn strftime('%Y:%m:%d %H:%M:%S - ', localtime),
"Sleeping '$to_sleep' seconds\n";
sleep $to_sleep;
}
__END__
Have it sleep for a very short time, <=1 sec, and check each time whether poll time has arrived. Incremental processor use will be negligible.
Edit: cron is fine if you know what interval you will use and don't intend to change frequently. But if you change intervals often, consider a continuously running script w/ short sleep time.
Depending on how fine grained your time resolution needs to be, there may be a need to write your script daemon style. Start it once, while(1) and do the logic inside the program (you can check every second until it's time to run again).
Perl's Time::HiRes allows very fine granularity if you need it.
I have an ASP.Net 3.5 website running in IIS 6 on Windows Server 2003 R2. It is a relatively small internal application that probably serves less than ten users at any given time. The server has 4 Gig of memory and shows that 3+ Gig is available while the site is active.
Just minutes after restarting the web application Performance monitor shows that there is a whopping 4,294,967,293 sessions active! I am fairly certain that this number is incorrect; at the time this reading there were only 100 requests to the website.
Has anyone else experienced this kind odd behavior from perf mon? Any ideas on how to get an accurate reading?
UPDATE: After running for about an hour the number of active sessions has dropped by 4. So it does seem to be responding to sessions timing out.
Could be an overflow, but my money's on an underflow. I think that the program started with 0 people, someone logged off, and then the number of sessions went negative.
Well, 2^32 = 4,294,967,296, so sounds like there's some kind of overflow occurring. Can't say exactly why.
We have the same problem. It looks like MS has a Hotfix available: http://support.microsoft.com/kb/969722
Update 9/10/2009: Our IT department contacted MS for the Hotfix. It fixed our issue. We are running .NET 2.0 if it matters any.
I am also showing a high number, currently 4,294,967,268.
Every time I abandon a Session, the Sessions abandoned count goes up by 1, and the Sessions Active count decreases by 1. Currently my abandoned session count = 16, so this number probably started at 4,294,967,84.
Is there a fix for this?
My counters were working fine, but one morning I logged in remotely to the production server, and the counter was on this huge number (which is as somebody mentioned very close to 2^32 indicating an underflow). But the only difference from the day before when everything worked was the fact that during the night, windows had installed updates.
So for some reason these updates caused this pretty annoying error.
Observing the counter a little more, I found out that whenever the application is restarted - after some time with no traffic, the counter starts correctly at zero. When users start logging on, it increments fine. When they start logging off again, it still decrements fine until it reaches what is supposed to be zero. At that point it goes bananas...
Sigh...
If you have to use your existing statistics, I opened the log file in Excel and used a formula to bring a more accurate value. I cannot guarantee its accuracy, but the results did look okay:
If B2 is the (aspnet_wp)\Sessions Active value , and the formula sits in C2
/* This one is quicker as it doesn't have to do the extra calculations */
=IF(B2>1073741824,4294967296-B2,B2)
Or
/* This one is clearer what is going on */
=IF(B2>power(2,30),(4*power(2,30))-B2,B2)
P.S. (I feel your pain - I have to explain why they have 4.2 billion sessions opening whereas a second earlier they had 0!)
