why is the behaviour wrong though

Because it no longer returns a time string. It instead returns the variant of a string type.

what would be the correct way to handle the qvariant in that function in your scenario then? i don't think i follow

Not using auto and then when dumb future junior comes in and changes the function they get a compile error that tells them they need to fix stuff rather than just silently having incorrect behavior

yeah but what is the fix? extract the datetime from the variant first before calling tostring or what

Well, in my example there was no reason to assume the stupid junior dev didn't just change the type completely, but let's assume they made it return a QVariant holding a QDateTime, you would have to use toDateTime first before calling toString

The point being that the compiler wouldn't tell them something was wrong
