commit e57f26c135b03f5dbde77aea24551b6a9fc20889

    Have correct_tm set tm_wday as well.
    
    The tm_wday field had been left uninitialized, which was causing
    some assertions to fail on Windows unit tests.
    
    Fixes bug 18977.

+  o Minor bugfixes (time handling):
+    - When correcting a corrupt 'struct tm' value, fill in the tm_wday
+      field. Otherwise, our unit tests crash on Windows.
+      Fixes bug 18977; bugfix on 0.2.2.25-alpha.
