How to det Date from String. QDate and Qtime?

[TheCeylann]

I have Date and Time values as String. I want to synchronize these values with QTime and Qdate and want the time to flow from the values I gave instead of Current time, how can I do this?

Here is mu finction

void MainWindow::on_syncdatebtn_clicked() 
{


   QStringList dtstr = dtcal.split(".");
    dtcal.remove(".");
    serial.send(QString::fromUtf8("WR+1160")+dtcal);
    serial.waitdata();
    QString getdtcal=serial.getString();
     serial.waitdata();
     QStringList getdtcalbuf = getdtcal.split(",");
     qDebug()<< getdtcalbuf;
QString Timeformat = getdtcalbuf[2]+"."+getdtcalbuf[3]+"."+getdtcalbuf[4];  
QString Dateformat = getdtcalbuf[5]+"."+getdtcalbuf[6]+"."+getdtcalbuf[7];
qDebug()<<Timeformat << "  "  << Dateformat;
     qDebug()<< dtcal;
     QTime Time =QTime::fromString(Timeformat,"hh.mm.ss");  
     QDate Date = QDate::fromString(Dateformat,"dd.MM.yy");
qDebug()<< Time << "  "<<Date;  //QTime(Invalid)    QDate(Invalid)
}

@TheCeylann said in How to det Date from String. QDate and Qtime?:

DateFormat "2.10.22"

This does not match the format "dd.MM.yy", also you should add 2000 to your year - QDateTime assumes 1900 if only two digits are given for the yeas.

The time is correctly converted:

QString Timeformat("21.25.15");
QString Dateformat("02.10.22");
QTime Time = QTime::fromString(Timeformat, "hh.mm.ss");
QDate Date = QDate::fromString(Dateformat, "dd.MM.yy");
qDebug() << Time << "  " << Date;
--> QTime("21:25:15.000")    QDate("1922-10-02")

Hi,

What is the content of your variables ?

Değişkenlerinizin içeriği nedir?

Hello
getdtcalbuf returns me

("CMD", "OK", "21", "12", "57", "2", "10", "22", "DHC", "\r\n")

This data comes to me from the serial port, I use the first two for control, the rest are in order;

getdtcalbuf[2] = hour
getdtcalbuf[3] = minute
getdtcalbuf[4] = second
getdtcalbuf[5] = day
getdtcalbuf[6] = month
getdtcalbuf[7] = year

And what is the content of your TimeFormat and DateFormat variables ?

On a side note, these variable names are misleading. They are the date and time values not their format.

@SGaist

TimeFormat "21.25.15"  

DateFormat  "2.10.22"

So is there any other way I can set it to custom instead of the system clock?

[SGaist]

The invalid date comes from a mismatch between your input string and the format.

Are you sure that your time input does not suffer the same issue ?

[TheCeylann]

@SGaist It doesn't happen when I set the time via String. But when I do it with current DateTime() it works fine.
i'm Sorry I forgot myself.

Sorry, Turkish is not one of the language I speak.
