+Subject: [PATCH 2/2] Correct certificate lifetime calculation
+
+sscg allows passing the certificate lifetime, as a number of days, as a
+commandline argument.  It converts this value to seconds using the
+formula
+
+  days * 24 * 3650
+
+which is incorrect.  The correct value is 3600.
+
+This effectively adds an extra 20 minutes to the lifetime of the
+certificate for each day as given on the commandline, and was enough to
+cause some new integration tests in cockpit to fail.
+
+Interestingly, 3650 is the old default value for the number of days of
+certificate validity (~10 years) so this probably slipped in as a sort
+of muscle-memory-assisted typo.
+
+Let's just write `24 * 60 * 60` to make things clear.
