+#      Some systems implement leap seconds by amortizing the leap second
+#      over the last few minutes of the day. The frequency of the local
+#      clock is decreased (or increased) to realize the positive (or
+#      negative) leap second. This method removes the time step described
+#      above. Although the long-term behavior of the time scale is correct
