+# hwclock.sh Set system clock to hardware clock, according to the UTC
+#               setting in /etc/default/rcS (see also rcS(5)).
+#
+# WARNING:      If your hardware clock is not in UTC/GMT, this script
+#               must know the local time zone. This information is
+#               stored in /etc/localtime. This might be a problem if
+#               your /etc/localtime is a symlink to something in
+#               /usr/share/zoneinfo AND /usr isn't in the root
+#               partition! The workaround is to define TZ either
+#               in /etc/default/rcS, or in the proper place below.
