Version: (using KDE 4.2.2) OS: Linux Installed from: Debian testing/unstable Packages In the message list, I select the Aggregation Mode to be "Current Activity, Threaded". This groups the messages into categories such as "Today", "Yesterday", "Last week". However, it seems that the division to weeks assumes the week starts on Monday. For example, today, Tuesday 28/4, messages from Sunday 26/4 show up under "Last Week". Here in Israel, weeks start on Sunday, and the "Country/Region&Language"/"Time&Dates" settings are correct; the messages should be under "This week" or "Two days ago" or whatever. (of course, the problem extends further, messages from Sunday 19/4, which should be under "last week", are under "two weeks ago" etc).
I've posted a patch that fixes this bug at reviewboard.kde.org.
SVN commit 972854 by tmcguire: Use 'first working day of week' setting to aggregate messages by date. Patch by Jonathan Armond <jon dot armond at gmail.com>, thanks! BUG: 190910 M +7 -4 model.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=972854
Indeed it now works for me. Should I (the reporter) change the status to "Verified", or wait for a more formal QA verification? Thanks for the fix, Shai.
