      1  1.1  kardel Notes on CPU clock oscillator tolerance with SunOS 4.1.1 and 4.1.3
      2  1.1  kardel 
      3  1.1  kardel A bug in SunOS 4.1.1 results in the kernel time losing 1 microsecond
      4  1.1  kardel per tick of the system clock. The bug was fixed (bugid 1094383) for
      5  1.1  kardel SunOS 4.1.1 and corrected in SunOS 4.1.3. The easiest way to fix this
      6  1.1  kardel is to replace the 4.1.1 binary clock.o with the corresponding 4.1.3
      7  1.1  kardel binary. Without this change it is necessary to use the tickadj program
      8  1.1  kardel included in this distribution with the -t 9999 option.
      9  1.1  kardel 
     10  1.1  kardel The tickadj option will work in all cases except when the kernel has
     11  1.1  kardel been modified to correct the CPU clock oscillator frequency using a
     12  1.1  kardel 1-pps signal from a precision source. The bugfix must be installed for
     13  1.1  kardel this wrinkle to work properly.
