When booting kernel-18.104.22.168-33.fc7, the time on the login screen is wrong. As well, the Gnome clock-applet shows the wrong time. The "date" command, however, gives the correct time.
When the computer is rebooted with kernel-22.214.171.124-27.fc7 the correct time appears on the login screen and in the clock-applet.
Is there a known issue with the clock setting with kernel-126.96.36.199-33.fc7?
