+Subject: [PATCH] tests: avoid false-positive in date-debug test
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When debugging an invalid date due to DST switching, the intermediate
+'normalized time' should not be checked - its value can differ between
+systems (e.g. glibc vs musl).
+

+
+* tests/misc/date-debug.sh: Replace the exact normalized time
+with 'XX:XX:XX' so different values would not trigger test failure.
