Hello, The need: 4-digit year support for short date formats to avoid issues like "10/11/12" dates.
This is just my initial conclusion from for the Qt date format issue: https://bugreports.qt.io/browse/QTBUG-59382?focusedCommentId=436861&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-436861 lt;dr: KF5 context: KCallendarSystem is part of the old APIs and the only code I found related to LC_TIME. So I've not found any common code KDE app can use instead of hard coding some internal logic in order to support non-Plasma environments and/or non-global settings. Basically even if an app implements locale name selection in its private settings, "pure" Qt code is not enough to support it in the discussed cases. Users may need alter date format globally (for all apps) by hand using environment's settings, setting e.g. yyyy-mm-dd. Or app developers may add private setting for that, one per app. Opinions welcome. -- regards, Jaroslaw Staniek KDE: : A world-wide network of software engineers, artists, writers, translators : and facilitators committed to Free Software development - kde.org KEXI: : A visual database apps builder - kexi-project.org calligra.org/kexi twitter.com/kexi_project facebook.com/kexi.project t.me/kexi_project Qt Certified Specialist: : linkedin.com/in/jstaniek <http://www.linkedin.com/in/jstaniek>
