Fedora time bug
The question of setting time comes up frequently. Setting the timezone and the system clock can be confusing, particularly if the machine is dual boot. Nowadays I don't see too many of those (a sign that Linux has grown up enough or just that it's cheap enough to run separate machines?), so the answer is usually simple: set the hardware clock to UTC, run ntpd and set your timezone correctly.
So when a local reseller called recently saying he couldn't get a Fedora Core 4 box to hold time upon reboot, I assumed he just didn't have things set right and referred him to the docs.
I was wrong.
