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.

I have 2 questions on the case recorder.
1- I am not sure how to restart an optimizaiton from where the recorder left off. I can read in the case reader sql file etc but can not see how this can be fed into the problem() to restart.
2- this question is maybe due to my lack of knowledge in python but how can one access to the iteration number from within an openmdao component (one way is to read the sql file that is constantly being updated but there should be a more efficient way.)
You can re-load a case back via the load_case method on the problem.
See the docs for it here.
Im not completely sure what you mean by access the iteration count, but if you just want to know the number of times your components are called you can add a counter to them yourself.
There is not a programatic API for accessing the iteration count in OpenMDAO as of version 2.3
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.

finally, here's a Code Project that seems to do something similar to what you want
My question is plain and simple. Can i run custom code in the updateHandler when I´ve executed a HKWorkoutSession and is listening for HeartRate samples? (Even when the Watch is locked from "wrist down" movement)
If this i possible what are my limitations?
I´m interested in processing the HeartRate data when my code receives them. I don´t have a device yet so I haven't been able to test it yet.
Would love your thoughts on this if anyone have experimented with an actual device.
Yes you can do this, I've had it append every HKSample that came back from my query onto an array, so when I resume the array is much larger. However UI won't update this way, on resume you need to update to the values you've received from the updateHandler.
Whether I should be doing this, or how far it can be pushed, I'm not sure.
Update
In the latest Xcode 7 beta you can get simulated workout data, so you won't need to install the Watch OS 2 beta on your device.
I'm currently writing a macro that performs a series of control sends and control clicks.
They must be done in the exact order.
At first I didn't have any sleep statements, so the script would just go through each command regardless whether the previous has finished or not (ie: click SUBMIT before finish sending the input string)
So I thought maybe I'll just put some sleep statements, but then I have to figure out how best to optimize it, AND I have to consider whether others' computers' speeds because a slow computer would need to have longer delays between commands. That would be impossible to optimize for everyone.
I was hoping there was a way to force each line to be run only after the previous has finished?
EDIT: To be more specific, I want the controlsend command to finish executing before I click the buttons.
Instead of ControlSend, use ControlSetText. This is immediate (like GuiEdit).
My solution: use functions from the user-defined library "GuiEdit" to directly set the value of the textbox. It appears to be immediate, thus allowing me to avoid having to wait for the keystrokes to be sent.
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.
