In my project i have a function which i only need to execute if the current time is between given 2 times. Note that the time is fetched from RTC so its 24hr. For example if current time is 23:00,start time is 20:00 and end time is 5:00 the function must execute and not execute otherwise.
if((fromhour>=now.hour() && fromminute>=now.minute()) || (tohour>=now.hour() && tominute>=now.minute()))
{
//Call function
}
I tried this code but not working as expected. please give a solution for this problem.
Guys i think i find a solution for this.
starttime=fromhour*100+fromminute;
stoptime=tohour*100+tominute;
current_time=currenthour*100+currentminute;
if(current_time>=starttime && current_time<=stoptime)
{
//Call function
}
Tell me if there is an improved or better way. Happy coding :)

I want to test a simple strategy based on time: every day at fixed time check some conditions and go long. every day at fixed time exit.
Whatever I try to get timeOpenCondition I get syntax error.
Tried things similar to:
EntryTime = if hour=0800 and minute=0
ExitTime = if hour=1400 and minute=0
It feels like I don't get the concept of how this works. Appreciate any help!
I saw this question online from an interview:
Suppose you have this code:
void myFunction(){
int time = clcTime();
while (clcTime()-time!=3600);
}
When clcTime() is a method that returns the seconds that passed since 00:00 of today.
(1). Find what this code snippet does.
(2). Some QA tester said this code fails at specific case. What's that case and how can you solve that issue?
(3). Another QA tester that during the day this code worked fine, but when he got to sleep - something went wrong. What can possibly be the problem and how can you solve it?
My attempt:
For (1), I think this function just suppose to run in a loop for an hour.
For (3), I think the problem is when the time variable get its value when the current hour of the day is in the range [23:00:00,23:59:59]. And that's because on that case, the value of time will be in the range [23*3600,23*3600 + 3599] and clcTime() can't return a matching value in the range [24*3600, 24*3600 + 3599]. So in that case, we know that the condition 'clcTime()-time' will never get a value of 3600 and we will get an infinite loop.
My suggestion for solving it is replacing the while line with those lines:
int measure = clcTime() - time;
int measureModulo = measure % 3600;
while (measure==0 || measureModulo!=0){
measure = clcTime() - time;
measureModulo = measure % 3600;
}
The only problem I still have is that I can't figure out (2) - I don't find any other problem with this code.
Do you have any idea what else can be problematic with this code?
Also, please feel free to correct me if I was wrong with what I wrote for (1) and (3).
Another problem with this code, and your fix, is that it checks clcTime() for an exactly matching value. If the system is busy and the loop doesn't get to run for more than a second, then it will miss the matching second and continue waiting for at least another hour.
Also there will be problems when the user changes the system clock or system time zone, when daylight savings time comes into or out of effect, when the clock is automatically adjusted for leap seconds, etc.
Laravel Task Scheduling has options like, everyMinute() which will run a command every minute. I want to know what is the time it actually starts executing. Is it when I run the server or any specific second of the minute?
I am trying to run a function depending on the time difference. Here's a pseudocode
Run myCustomFunction() if diffInMin(now, customTime) <= 1
I thought it will run 1 time but it ran twice every time.
The scheduler usually runs every minute right around the zero secound mark based on the server's current time as #apokryfos mentioned.
Assuming the customTime is a fixed DateTime, what makes you think the code you wrote will only run once?
When now() === customTime the diffInMin() would be zero so the
condition diffInMin(now, customTime) <= 1 will evaluate to true.
The next minute, the diffInMin() would be 1, so the
condition diffInMin(now, customTime) <= 1 will still evaluate to true.
I am working on an application where there are read only screens.
To test whether the data is being fetched on screen load, i want to set some wait time till the screen is ready.
I am using python to record the actions. Is there a way to check the static text on the screen and set the time ?
You can simply use
snooze(time in s).
Example:
snooze(5)
If you want to wait for a certain object, use
waitForObject(":symbolic_name")
Example:
type(waitForObject(":Welcome.Button"), )
The problem is more complicated if your objects are created dynamically. As my app does. In this case, you should create a while function that waits until the object exists. Here, maybe this code helps you:
def whileObjectIsFalse(objectID):
# objectID = be the symbolic name of your object.
counter = 300
objectState = object.exists(objectID)
while objectState == False:
objectState = object.exists(objectID)
snooze(0.1)
counter -= 1
if counter == 0:
return False
snooze(0.2)
In my case, even if I use snooze(), doesn't work all the time, because in some cases i need to wait 5 seconds, in other 8 or just 2. So, presume that your object is not created and tests this for 30 seconds.
If your object is not created until then, then the code exits with False, and you can tests this to stop script execution.
If you're using python, you can use time.sleep() as well
I read a lot but cannot find something that works.
I have a php query that sets the user status to 1 when logged in, and 0 when logged out.
At the moment, I have a timer for inactivity but this will not work if the user closes the browser.
I know the solution is somehow to use javascript to periodically call the server using ajax. But I am not sure how to do that
Any help is much appreciated!
On page:
if ($_SESSION['last_action'] + (10*60) < time()) // Check if last action time wasn't less than 10 minutes ago.
{
// Log user out.
}
else {
$_SESSION['last_action'] = time();
}
