+Subject: [PATCH] Fix meridian type in kadmin datetime parser
+
+The meridian suffix is typed as "Number" in kadmin YACC file for
+datetime parsing, while it should be using the "Meridian" enumeration
+one.
+
+This results in invalid Meridian value on 64-bit IBM zSystems (s390x),
+causing core dumped errors on most kadmin commands where meridian
+suffices are used.
