QSettings ini file does not keep file creation date

With Qt 5.3 when a ini file is modified by QSettings class the creation date of the file is kept, and the modification date is overwritten.

From Qt 5.4 when QSettings writes the file it erase both the creation and modification date of the file.

It seems it comes from the usage of QSaveFile to save safely the file.

Is this behaviour change an unwanted side effect or is it intentionnal ?
Is there a way to get back to the pevious behaviour ?

Thanks
