560788 - message list displays date incorrectly with some regional settings

Status: RESOLVED INVALID

(Thunderbird :: Folder and Message Lists, defect)

Description

[frenk]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.9) Gecko/20100317 Thunderbird/3.0.4

In the message list, when a message has been received in the current day, only the time is displayed (without date). That time is not displayed correctly with some regional settings, in particular I noticed that with Italian (Switzerland) the time is 12 hours instead of 24, kind of annoying because it lacks AM/PM so it's effectively impossible to determine if it's morning or evening.

Reproducible: Always

Steps to Reproduce:
1. Set your Windows regional settings to Italian (Switzerland)
2. Set your OS time to for ex. 21:05
3. Send yourself a message
Actual Results:  
In the list of messages you will see your message with "09:10" in the Date column

Expected Results:  
In the list of messages you should see your message with "21:10" in the Date column

This works for me with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.9) Gecko/20100317 Thunderbird/3.0.4.

Have you tried safe mode? (see https://support.mozillamessaging.com/en-US/kb/Safe+Mode for more information)

Ok, in fact it's working also for me on a x64 windows7 box (english OS, english thunderbird), but it's definitely not working on my notebook (windows 7 en, thunderbird *italian*): Mozilla/5.0 (Windows; U; Windows NT 6.1; it; rv:1.9.1.9) Gecko/20100317 Thunderbird/3.0.4

On that machine I have these regional settings: Format: Italian (Switzerland), Current Location: Switzerland.

Also there in safe mode.
I'll attach a couple of screenshots.

Pasquale can you reproduce ?

I can confirm but I don't think that is TB related. It seems Windows 7 related as you can see on your screenshot on comment #4: you have changed "short time" rightly but at "Examples" section you see an invalid short time because no AM\PM is displayed (and then if Windows 7 can't display rightly also TB can't).
Probably some setting is missing and\or is a "simple" Windows 7 bug.

ps: if your TB test mail you open your source code, you can see that the "Date" header is right: it's only a view error.

ps: if you display "source code" in your TB test message, you can see that mail "Date" header is right: it's only a display issue.

I think you are right, there is something weird with the Windows time format. I'll try to file a report (finding a place to do this has proven more difficult than I thought).
The weird thing is that in different places/programs the short time format is the correct one (for ex. if you write DateTime.Now.ToShortTimeString() in .NET). And also the clock in the windows taskbar.

I have verified that Outlook 2007 with same settings, display date as TB: this is a bug of Windows 7 OS.

I close this issue as Invalid (because isn't related to TB). Feel free to reopen it if I'm wrong.
