THANK you, Andrey. I reported this some time ago, but the best I ever got was people asking me to confirm my setup. http://qa.mandrakesoft.com/show_bug.cgi?id=3125 I'm glad that someone who understands the kernel was able to discover the source of this problem. Michael (Reinsch), if you look at my bug report, you'll see that CLOCK_SYNC set to "yes" (as per the default install of the rpm) doesn't help. And I keep my config pretty vanilla -- other than the fact that it's running cooker... :) In my opinion, if this is something that's "broken" at kernel config level, no band-aid fixes with scripts (whether it works or not) is the correct solution. Patching the source of any problem seems more logical. Granted, I don't know the reason (if one) for the setting always being set to GMT, but considering the cited reports a fix would make several users happy. Oh, and I'd be more than happy to test any patches. - John
