Bug ID: 52002
           Summary: comctl32:datetime fails in the Arabic (Egypt) locale
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: comdlg32
          Assignee: [e-mail]
          Reporter: [e-mail]

comctl32:datetime fails in the Arabic (Egypt) locale:

datetime.c:212: Test failed: String mismatch ("12 hh" vs "hh 12")
datetime.c:798: Test failed: Expected 08/11/2021, got 2021/11/08

This failure happens as soon as one sets UserDefaultLCID to 0xc01 (Settings ->
Time & Language -> Regional format -> Arabic (Egypt)).

Note: the reason it worked up to 2021-10-21 is because before then
UserDefaultLCID was incorrectly set to English in the w10pro64-ar VM. Then I
upgraded the VM to Windows 21H1 and in the process I recreated the Arabic
snapshot which got the intended locale this time. The current settings are:

SystemDefaultLCID            0c01
UserDefaultLCID              0c01
ThreadLocale                 0c01
SystemPreferredUILanguages   0409
UserDefaultUILanguage         0401
ThreadUILanguage             0401
