On my tests, the gnome-panel clock is displaying exactly what the system's clock indicates, meaning this is not a problem with the gnome- panel clock, but simply that the computer's internal clock might not be synchronized with that of the other computer you're comparing it to.
You might try synchronizing all your computers to the same time server. On Ubuntu, use this command on a terminal: sudo ntpdate pool.ntp.org Make sure to synchronize your other computers to the same time server (pool.ntp.org). Please report back and let me know if after synchronizing all clocks to an authoritative, reliable time source, they are still running out of sync. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/731570 Title: Panel clock is always exactly one second late -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
