@asgs Same thought as I was going through it.

It loses data in the conversion as QDate does not have time included.
If this gives any clues:
qml: Mon Feb 21 08:33:22 2022 GMT-0700
setDate() QDate("2022-02-21")
date() QDate("2022-02-21")
qml: Sun Feb 20 17:00:00 2022 GMT-0700
The code that prints this (js):
let date = new Date()
console.log(date)
dobj.setDate(date)
let ndate = dobj.date()
console.log(ndate)
C++:
Q_INVOKABLE QDate date(){
qDebug() << "date()" << m_date;
return m_date;
}
Q_INVOKABLE void setDate(QDate ndate){
qDebug() << "setDate()" << ndate;
m_date = ndate;
} -
@gosubinit very likely. Not going to mess with this at all. Just going to convert to string and send that to database to begin with. So I only pass strings.

Found this somewhere and started crying
Holy f-ing hell!
Why do the small things have such fucked up corner cases?
This is very likely a giant bug with Qt, but how does this even happen?
I am using Qt with QML and sending data to a database on the backend. I call functions in QML from a Date JS object (property actually, but it calls functions) to set the date as a QDate. This is stored in the database as yyyy/MM/dd. This is fine. When I read the date out I convert it back from string to QDate and send this object to QML. Which then converts this to a Date object in JS in QML.
But at the point where it converts from a QDate to a Date object it loses an entire day. Seriously? You didn't gain a day going from Date -> QDate, but you lose a day going from QDate -> Date?
How long has QML and Qt been around? At least 5 to 10 years. How has this bug lasted this long? I don't want to do a bug report. I will, but I don't want to .
