I have a few linux boxes at work performing thankless http server duties and I have never been excessively worried about time or even date on those machines until someone pointed out to me a couple of weeks ago that a script used to retrieve documents in a database was setting the date of the query to February 2037. I checked and lo, that was the system date of the machine! After a little bit of searching, I found out the time server I was using (rolex.usg.edu I think, for about 4 years I guess) was either returning garbage or was returning something suddenly my netdate utility would not understand. I have been updating time each day in the AM (cron job) from the same machine (and others, I need to check) for years. I switched to another time server and all is good for now, with one exception. I have the timezone set to CST (Chicago), since that's where I am, but it sets the offset to only 6 hours instead of 7. To be honest, I do not know if this has always been the case (when rolex was working) or if this is new, as I say, I am not too worried about time/date on this machine, but 2037 was a bit much.... The same happens if I set the system clock from the CMOS instead of the time server. The CMOS is also set to UTC and correct. It is as if my timezone is wrong, but I reloaded from a *believed good* original and no dice.
What am I doing wrong? Didier KO4BB _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
