1.1 ! misho 1: Notes on CPU clock oscillator tolerance with SunOS 4.1.1 and 4.1.3 ! 2: ! 3: A bug in SunOS 4.1.1 results in the kernel time losing 1 microsecond ! 4: per tick of the system clock. The bug was fixed (bugid 1094383) for ! 5: SunOS 4.1.1 and corrected in SunOS 4.1.3. The easiest way to fix this ! 6: is to replace the 4.1.1 binary clock.o with the corresponding 4.1.3 ! 7: binary. Without this change it is necessary to use the tickadj program ! 8: included in this distribution with the -t 9999 option. ! 9: ! 10: The tickadj option will work in all cases except when the kernel has ! 11: been modified to correct the CPU clock oscillator frequency using a ! 12: 1-pps signal from a precision source. The bugfix must be installed for ! 13: this wrinkle to work properly. ! 14: ! 15: Dave Mills (mills@udel.edu)
