+<title>Creating the setclock script</title>
+
+<para>
+The following script is only for real use when your hardware clock (also
+known as BIOS or CMOS clock) isn't set to GMT time. The recommended
+setup is setting your hardware clock to GMT and have the time converted
+to localtime using the /etc/localtime symbolic link. But if you run an
+OS that doesn't understand a clock set to GMT (most notable are
+Microsoft OS'es) you might want to set your clock to localtime so that
+the time is properly displayed on those OS'es. This script will reset
+the kernel time to the hardware clock without converting the time using
+the /etc/localtime symlink.
+</para>
+
+<para>
+If you want to use this script on your system even if you have your
+hardware clock set to GMT, then change the UTC variable below to the
+value of <emphasis>1</emphasis>.
