+README file for directory ./kernel/sys of the NTP Version 3 distribution
+
+This directory contains system header files used by the clock discipline
+and STREAMS modules in the .. (./kernel) directory.
+
+If the precision-time kernel (KERNEL_PLL define) is configured, the
+installation process requires the header file /usr/include/sys/timex.h
+for the particular architecture to be in place. The file timex.h included
+in this distribution is for Suns; the files for other systems can be
+found in the kernel distributions available from the manufacturer's
+representatives.

+ *
+ * MAXTC establishes the maximum time constant of the PLL. With the

+ * this can occur only if something has failed or is operating out of
+ * tolerance, but otherwise the PLL continues to operate in a stable
+ * mode.
+ *
+ * MAXPHASE must be set greater than or equal to CLOCK.MAX (128 ms), as
+ * defined in the NTP specification. CLOCK.MAX establishes the maximum
+ * time offset allowed before the system time is reset, rather than
+ * incrementally adjusted. Here, the maximum offset is clamped to
+ * MAXPHASE only in order to prevent overflow errors due to defective
+ * protocol implementations.
+ *
+ * MAXFREQ is the maximum frequency tolerance of the CPU clock
+ * oscillator plus the maximum slew rate allowed by the protocol. It
+ * should be set to at least the frequency tolerance of the oscillator
+ * plus 100 ppm for vernier frequency adjustments. If the kernel
+ * PPS discipline code is configured (PPS_SYNC), the oscillator time and
+ * frequency are disciplined to an external source, presumably with
+ * negligible time and frequency error relative to UTC, and MAXFREQ can
+ * be reduced.
+ *
+ * MAXTIME is the maximum jitter tolerance of the PPS signal if the
