Can not convert QString to QDateTime

Question

I have to convert QString to QDateTime by QDateTime::fromString method. I have QString object which contains "Wed, 13 Jun 2018 12:52". But when I use it QDateTime::fromString returns invalid object and I don't knew why. I use "ddd, MM-MMM-yyyy HH:MM" format. Could anyone tell me what I doing wrong?

My code:

QString tempDate; //Wed, 13 Jun 2018 12:52
QDateTime::fromString(tempDate, "ddd, MM-MMM-yyyy HH:MM"); //returns invalid obj

Answer 1

Your QDateTime format does not correspond to your input string.

Wed, 13 Jun 2018 12:52 should be matched with ddd, dd MMM yyyy HH:mm .

See QDateTime::fromString .

Also, make sure you're using the correct locale when doing the conversion, as ddd and MMM are localized. Either change the local with QLocale::setDefault , or with QLocale::toDateTime :

QLocale(QLocale::English).toDateTime(tempDate, "ddd, dd MMM yyyy HH:mm");

Answer 2

QDateTime startTime = QDateTime::fromString (QString("1970-07-18T00:00:00"), Qt::ISODate);
