+From: Guillaume Bourcier <guillaumebourcier@...>
+
+The algorithm computing daylight saving time incorrectly adds a day for
+each month after January for leap years. The clock shift from/to DST can
+be delayed if the last Sunday of a transition month is exactly seven
+days before the first of the following month.
+
+This change adds a day for the February month only.
