Every time I reboot my SUN 3/50M I get the message that the clock lost 29 days. While running the clock slows done about 10 minutes per hour, I avoid this by speeding up the clock rate ( date -annn.sss ) but having to reset the date every time I boot is a pain in the neck. Has anybody experienced this problem? Is it a hardware bug.... I tried pulling out the lithium battery and short-circuiting the electrolitic capacitor in order to reset the Intersil ICM7170 but nothing happened except that I got the message the the tod clock wasn't initialized. Any pointers.... The header isn't completely correct because I'm not in Cupertino but in Ivrea, Italy and read news through our link to Cupertino.

Which means that your clock only registers 50 minutes for every 60 that pass. Kinda like running a US spec AC clock in Europe. The clock would expect 60 hz but get 50 hz, causing it to slow down 10 min per hour. But a clock running on a lithium battery would be DC, no?? And DC should not be affected by the change in Hz in the AC line. Is it possible that the capacitator is not matched to the battery correctly? (Now that I think of it, when I use Kodak Lithium 9-volts to back up my alarm clock, rather then Alkaline 9-volts, the clock gains about a min per hour, so choice of battery could be a factor. Can anyone explain my problem w/ lithium 9 volts either???) Good luck. -JimC -- batcomputer!cloos@cornell.UUCP |James H.

There is a bug in SunOS that causes the clock to do strange things.
This has been discussed at length in comp.sys.sun. A patch is available
from the sun-spots archive server at Rice.
[ This has nothing to do with Xenix, etc. Followups are in comp.unix.questions ]

Oh well...... Two of the files in the SunRPC distribution (contained in the archives) suffer from the infamous dot-on-a-line-by-itself disease. I hope to take care of the problem in the very near future (I may just ask the author to repack those files with a better mail packer). The afflicted files are "rpcsrc.doc.11" and "rpcsrc.doc.13". Sorry for the inconvenience. Finally, what new year would be complete without a widespread and serious bug to plague everyone. No, I'm not talking about the flu. I'm talking about a disturbance in the temporal plane: the now infamous drifting clock bug. As most of you probably know by now, there is a bug in SunOS that, as of the beginning of the year, makes the TOD clock drift or otherwise behave oddly. Chuq at Sun has been kind enough to send a patch to Sun-Spots for this bug. I recommend this patch over all others---it's straight from Sun. It is all contained in the next message. I felt it important enough to pull it out of the queue of waiting message and run it immediately.

If you have any questions or problems, please call Sun Tech Support] chuq Sun Tech Support There exists a problem for all Sun3 (68020) machines running SunOS Releases 3.0-3.5, and all Sun4 (SPARC) machines running SunOS Release Sys4-3.2 FCS and Sys4-3.2L GAMMA. This problem does not exist for Sun-2's. As of Jan 1 00:00 1988, the clock routine in the kernel will put the clock chip into an uncertain state if you attempt to set the date. The visible effects of this is to 1) cause the message WARNING: TOD clock not initialized -- CHECK AND RESET THE DATE! to appear while booting vmunix, and to 2) cause the system date to start to drift widely. Any attempts to actually *set* the date will have only a temporary effect (i.e., the date you set will be good for about 30 seconds). In order to solve this problem, you must patch both the kernel and system object files. [[ NOTE that there are three separate patches.

"dictionatary", because diction and dictation are differentative.
