Annotation of embedaddon/ntp/util/README, revision 1.1

1.1     ! misho       1: README file for directory ./util of the NTP Version 4 distribution
        !             2: 
        !             3: This directory contains the sources for the various utility programs.
        !             4: See the README and RELNOTES files in the parent directory for directions
        !             5: on how to make and install these programs.
        !             6: 
        !             7: The ntptime.c program checks the kernel configuration for the NTP user
        !             8: interface syscalls ntp_gettime() and ntp_adjtime().  If present, the
        !             9: current timekeeping data are displayed.  If not, a dissapointment is
        !            10: displayed.  See the kernel page file in the HTML documentation in
        !            11: distribution for further details. ntptime will be built be if configure
        !            12: believes your system can use it.
        !            13: 
        !            14: The jitter.c program can be used to determine the timing jitter due to
        !            15: the operating system in a gettimeofday() call.  For most systems the
        !            16: dominant contribution to the jitter budget is the period of the hardware
        !            17: interrupt, usually in the range 10 us-1 ms.  For those systems with
        !            18: microsecond counters, such as recent Sun and certain HP and DEC systems,
        !            19: the jitter is dominated only by the operating system.
        !            20: 
        !            21: The timetrim.c program can be used with SGI machines to implement a
        !            22: scheme to discipline the hardware clock frequency.  See the source code
        !            23: for further information.
        !            24: 
        !            25: The byteorder.c and longsize.c programs are used during the configuration
        !            26: process to determine the byte order (little or big endian) and longword
        !            27: size (32 or 64 bits).  See the configure scripts for further details.
        !            28: 
        !            29: The testrs6000.c program is used for testing purposes with the IBM
        !            30: RS/6000 AIX machines. Bill Jones <jones@chpc.utexas.edu> reports:
        !            31: "I could not get a tickadj of less than 40 us to work on a RS6000.
        !            32: If you set it less than 40 us do so at your own risk!"
        !            33: 
        !            34: The tickadj.c program can be used to read and set various kernel
        !            35: parameters affecting NTP operations. See the tickadj page in the HTML
        !            36: documentation for further details.  tickadj will be built if configure
        !            37: believes your system can use it.
