-The <TT>tickadj</TT> program reads, and optionally modifies, several timekeeping-related
-variables in the running kernel, via <TT>/dev/kmem</TT>. The particular
-variables it is concerned with are <TT>tick</TT>, which is the number of
-microseconds added to the system time during a clock interrupt, <TT>tickadj</TT>,
-which sets the slew rate and resolution used by the <TT>adjtime</TT> system
-call, and <TT>dosynctodr</TT>, which indicates to the kernels on some machines
-whether they should internally adjust the system clock to keep it in line
-with time-of-day clock or not.
-
-<P>We have a report that says starting with Solaris 2.6 we should
-leave <I>dosynctodr</I> alone.
-<A HREF="solaris-dosynctodr.html">Here is the report</A>.
-
-<P>By default, with no arguments, <TT>tickadj</TT> reads the variables
-of interest in the kernel and displays them. At the same time, it determines
-an "optimal" value for the value of the <TT>tickadj</TT> variable if the
-intent is to run the <TT>ntpd</TT> Network Time Protocol (NTP) daemon,
-and prints this as well. Since the operation of <TT>tickadj</TT> when reading
-the kernel mimics the operation of similar parts of the <TT>ntpd</TT> program
-fairly closely, this can be useful when debugging problems with <TT>ntpd</TT>.

+<h4>Synopsis</h4>
+
+<tt>tickadj [ -Aqs ] [ -a <i>tickadj</i> ] [ -t <i>tick</i> ]</tt>
+
+<h4>Description</h4>
+
+The <tt>tickadj</tt> program reads, and optionally modifies,
+several timekeeping-related variables in the running kernel in some
+machines, via <tt>/dev/kmem</tt>. The particular variables it is
+concerned with are <tt>tick</tt>, which is the number of
+microseconds added to the system time during a clock interrupt,
+<tt>tickadj</tt>, which sets the slew rate and resolution used by
+the <tt>adjtime</tt> system call, and <tt>dosynctodr</tt>, which
+indicates to the kernels on some machines whether they should
+internally adjust the system clock to keep it in line with
+time-of-day clock or not.
+
+<p>Note that this program does NOT work in some kernels, in
+particular Solaris 2.6 or later. See the <a href=
+"solaris-dosynctodr.html">report</a>.</p>
+
+<p>By default, with no arguments, <tt>tickadj</tt> reads the
+variables of interest in the kernel and displays them. At the same
+time, it determines an "optimal" value for the value of the <tt>
+tickadj</tt> variable if the intent is to run the <tt>ntpd</tt>
+Network Time Protocol (NTP) daemon, and prints this as well. Since
+the operation of <tt>tickadj</tt> when reading the kernel mimics
+the operation of similar parts of the <tt>ntpd</tt> program fairly
+closely, this can be useful when debugging problems with <tt>
+ntpd</tt>.</p>
+
+<p>Note that <tt>tickadj</tt> should be run with some caution when
+being used for the first time on different types of machines. The
+operations which <tt>tickadj</tt> tries to perform are not
+guaranteed to work on all Unix machines and may in rare cases cause
+the kernel to crash.</p>

-Fiddling with kernel variables at run time as a part of ordinary operations
-is a hideous practice which is only necessary to make up for deficiencies
-in the implementation of <TT>adjtime</TT> in many kernels and/or brokenness
-of the system clock in some vendors' kernels. It would be much better if
-the kernels were fixed and the <TT>tickadj</TT> program went away.&nbsp;
