The bios on this machine DOES NOT use UTC and the UTC box was unchecked during installation. Does that make a difference? I also see that since setting the time correctly about 5 hours ago, time has gained 5 minutes. I recall msgs sometime ago on this list about the clock gaining time in rawhide, so all I may have been seeing was time creep and not an erroneous EDST -> EST. -- fedora-test-list mailing list fedora-test-list@...

Does booting with 'nohz=off' fix the clock creep? -- Adam Williamson Fedora QA Community Monkey IRC: adamw \| Fedora Talk: adamwill AT fedoraproject DOT org http://www.happyassassin.net -- fedora-test-list mailing list fedora-test-list@...

If you use UTC for the hardware clock, then the right thing is always done with regard to DST. If you use localtime, then Linux assumes that the hardware clock contains the correct local time at boot. The DST adjustment will take place if the machine is running at the time of the transition, and the correct time will be saved if the machine is rebooted after that. If the machine is off at the time of the transition and you don't set the hardware clock, the time will be an hour off at boot. > > I also see that since setting the time correctly about 5 hours ago, time > has gained 5 minutes.

If the machine is connected to the Internet, you should consider using NTP to keep your clock in line. > > -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu http://www.math.clemson.edu/~mjs -- fedora-test-list mailing list fedora-test-list@...

The machine was off during the transition. That explains it. Also, I used to use NTP, but transistion to the desktop took so long I abandoned it. "Time" to try again. Thanks for the explanation.
