PySnooper has elapsed time in the outpoot and I get used to it's convenience, however I can't find it in Snoop.
Is there a way to have elapsed time in Snoop?

I hope everyone is doing well.
I am working on a time series project to predict hourly the waiting time (idle time) of a zone.
The idle time of a zone at a given hour is the average idle time of vehicles that start to wait at the given hour in that zone, and the idle time of a vehicle is the amount of time a vehicle should wait in that zone to be booked. For example, if we predict at 16h00 for zone A, a value of 90 minutes, it means a vehicle that starts to wait in this zone between 16h00 and 17h00 will wait 90 minutes to be booked.
For our idle time (our ground truth), at a given hour B, we have to wait 2 days (48 hours) to establish the complete ground truth value for hour B since we have to wait a maximum of two days for vehicles that start to wait at B and are not booked yet. So each time we want to make a prediction, the last 48 points are unstable. For example, if we want to make a prediction at time n, the ground truth of n-1 is partial and incomplete, and we have to wait 48–1 = 47 hours to establish the final value of the waiting time at n-1.
We can resume that problem as the recent past data at prediction time is changing and not fixed.
The following image illustrates what I explained above.enter image description here
My questions are :
Is this kind of behaviour known in the time series field? If that's the case, does it have a specific name?
2-How to mix stable and unstable points in order to make accurate predictions?
Any suggestions? and thank you ahead of time:)
I wrote a program for a LED display. The program allows to set the refresh rate via webconfiguration. To meet the refresh rate I measure the processing time of a loop. At the end I calculate the delay and wait until the next loop.
e.g. Refresh Rate 5 Hz -> 200 milli seconds for one loop. 50 milli seconds computing time results in 150 milli seconds delay.
The ratio of process time (50 milli seconds) to total time (200 milli seconds) indicates the processor load of my program. But to find the optimal setting, I need the actual total processor load. And not only that of my program. But since I don't know the real processor load of the delay() (in which WIFI etc. is done), I don't really know the processor load. In other words, I don't know how much time the system spends doing system tasks in the delay(150).
Is there a way to find out how much of a delay is actually used for system tasks before the processor truly waits?
In other words, I'm looking for a way to get the kernel time within a certain time frame.

Is there any way to know the time taken for each action to finish in Robot Framework???
Like For example, I want to rotate screen 90 degrees 10 times, how to time it or how to average the time taken by these actions??
The simplest solution is to get the current time, run your keyword or keywords, then get the current time again, Then, subtract the starting time from the ending time.
Robot framework provides a DateTime module that has functions to support this. For example, Get current date can return the current date and time. Subtract date from date can return a timedelta which can be formatted to days, hours, minutes, seconds, and milliseconds.
You can see it in your report.
http://robotframework.org/QuickStartGuide/report.html
Elapsed Time: 00:00:00.284
It is also available at Keyword Level in the Test Execution Log.
${date1} = Get Current Date
TestCase_To_Rotate_Screen_10_Times
${date2} = Get Current Date
${actiontime} = Subtract Date From Date ${date2} ${date1}
Problem that occurs to me:
In the case of the United States where a one-hour shift occurs at
02:00 local time, in spring the clock jumps forward from the last
moment of 01:59 standard time to 03:00 DST and that day has 23 hours,
whereas in autumn the clock jumps backward from the last moment of
01:59 DST to 01:00 standard time, repeating that hour, and that day
has 25 hours.[37] A digital display of local time does not read 02:00
exactly at the shift to summer time, but instead jumps from 01:59:59.9
forward to 03:00:00.0.
And UIDatePicker is not given opportunity to set 02:00:00 time, when DST occurs. How it is possible to fix in UIDatePicker to be able to chose that time?
NSTimeZone is an abstract class that defines the behavior of time zone objects. Time zone objects represent geopolitical regions. Daylight Savings is also managed with that class. It can be done in one of the ways:
systemTimeZone:
The time zone currently used by the system. If the current time zone cannot be determined, returns the GMT time zone.
defaultTimeZone:
The default time zone for the current application. If no default time zone has been set, this method invokes systemTimeZone and returns the system time zone.
localTimeZone:
An object that forwards all messages to the default time zone for the current application. The local time zone represents the current state of the default time zone at all times.
with the localTimeZone class method, you can get a relative time zone object that decodes itself to become the default time zone on any computer on which it finds itself.
I have to display a timer in 10th second for a sport competition. I have do this using the OnTimer event of a TTimer. the interval is set to 100. My routine display the current min:sec.10th (ex.: 02:45.7 ) correctly but it seem that my timer loose about 4 second at each minutes if I comp. to normal clock.
There is a better way to get a time accuracy timer in Delphi XE2 (or XE3) ?
You can use a timer to display the current value of the clock, but use a different approach to calculate the elapsed time.
You have to know that Windows timers are not time accurate, and even if you set it to elapse every 100 milliseconds, it can take more to fire the OnTimer event and even it can miss some intervals if for some reason elapses two or more times before your application process it.
You can, for example, use the system high-resolution performance counter to track times with nano-second accuracy.
You can also use the Delphi TStopwatch class, which encapsulates the system calls and falls back to other method (GetTickCount) if the high resolution performance counter is not available in your machine.
Take also a look at the How to Accurately Measure Elapsed Time Using High-Resolution Performance Counter delphi.about.com article.
