File System view/model How to change format of date modified?

[basimchowdhury]

I have a QTreeView showing the contents of a QFileSystemModel. The last column shows the date modified for each item, but I want to change the format of this to be shorter. Right now it shows it in dd MMM YYYY HH:MM:SS i.e "31 May 2019 12:01:09" format. I want to change this to more of a "31/5/19 12:01:08" format.

Just do it like this then :)
dd/M/yy HH:MM:SS should work.

Never used a QFileSystemModel before, but I guess you are using QDateTime QFileSystemModel::lastModified(const QModelIndex &index) const (wow, code as hyperlink actually works).
So when you set your data to your model, you simply convert the QDateTime, which you recieve, to the format of your choice.

You can convert fromString to QDateTime and vice versa (with QDateTime::toString("dd/M/yy HH:MM:SS")).

EDIT:
I forgot about your QTreeView... Just set the TreeView-Item-Text to QDateTime::toString("dd/M/yy HH:MM:SS"). Then it should display the right format.
