+Subject: [PATCH] Fix docs generation for datetime with doxygen 1.11.0
+
+It seems that as of the below commit, doxygen changed its handling of
+parsing backticks in comments such that it now fails to properly
+generate documentation for the entire datetime.h file.  Fix this by
+closing the open backtick.
+
+Also update the actual, non-documentation, header to match for
+consistency, even if non-matching backticks are not a problem there.
+
+See: https://github.com/doxygen/doxygen/commit/f18767307be20ca8d2ca81f74cc1f3446205282b
+
+Closes #24814.
