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.
