Release Notes


The following changes are in the version 3-5.85 distribution relative to the previous 3.5f version.

  1. The automatic build procedure has been replaced with GNU autoconfigure. This should make porting to nonstandard machines and operating systems much easier and should simplify the maintenance for multi-architecture sites. See the ./WHERE-TO- START, ./INSTALL and ./README files for a brief overview of the new building and installing procedures. See the the building and installing pages in the HTML documentation for further information.

  2. A clock driver (type 11) is included for the Arbiter 1088A/B GPS Receiver.

  3. The Windows NT build procedure is changed. See the ./util/wininstall directory for further information.

  4. A clock driver (type 11) is included for the Arbiter 1088A/B GPS Receiver.

  5. The HTML documentation has been edited and updated to correct outdated information and minor typographical errors. A new page has been added for the Arbiter 1088A/B GPS Receiver.

  6. The xntpd daemon now calculates the authentication delay automatically, so it no longer needs to be specified for each architecture and operating system. The -e command-line switch has been removed from the xntpd program. The authdelay configuration option has been removed.

  7. The auth, monitor, pll and stats flags are enabled by default. The bclient and pps flags are disabled by default.

The following changes are in the version 3.5f distribution relative to the previous 3.4y version.

  1. Please note the scripts for configuring radio clock drivers do not work. See the building and installing documentation for specific information.

  2. The documentation has been completely reworked in HTML format suitable for web browsing.

  3. The automatic build procedure has been improved to

  4. Three TrueTime reference clock drivers, which did slightly different things with each model, have been replaced with one driver (type 5) that works with all models. Two new reference clock drivers have been added, one for the Bancomm IRIG interface, the other for the TrueTime GPS-VME interface. Both of these work only with the HP architecture.

  5. There is a new pps option to the xntpdc program and configuration file enable/disable command, which enables or disables the PPS precision time control signal for both the PPS clock driver and kernel PPS interface, where available. This is primarily intended for situations where external equipment has malfunctioned or the signal has become excessively noisy.

  6. The precision configuration file command and xntpdc command have been removed; the precision variable quantity is now determined automatically and cannot be changed.

  7. The authenticate and monitor commands in xntpdc have been removed; the functions formerly provided by these commands are now provided by the enable and disable commands.

  8. Fixed minor problems peculiar to different machines and system environments. Fixed minor problem in the PPS interfaces and mitigation rules. See the ./patches directory for details.

Version 3.5 has been compiled and run on at least the following machines, operating systems and compilers. In all known cases, if the gcc compiler eats it with some success, the cc compiler also enjoys the meal; the converse is not always true. Note that, while all clock drivers have been compiled, only certain ones have been tested with each machine and operating system.

Previous versions have been compiled and run on at least the following machines, operating systems and compilers.
