The resulting hwclock program works on all architectures. -There are some kernel bugs in the handling of /dev/rtc on some i386 hardware, -so under certain circumstances where hwclock fails one has to give it the ---directisa flag to let hwclock do the clock access itself (which works) -rather than leave it to the kernel.

That is the code found in the util-linux-2.9q clock -directory. Unfortunately, this new version didnt work on Sparcs -and in util-linux-2.9r this code was moved to the clockB subdirectory. - - -Executive summary: -clock/hwclock is claimed to be good (but may need the --directisa flag). - - -Comments, bug reports etc are welcome. -Note that the source contains a rather detailed description of the clock -hardware involved.
