I mention it more as a test, than anything else. But if yours is always on, it's hard to do such a test. > I know nothing about CMOS battery. This is an old system It's a small battery somewhere on the motherboard, often a coin sized battery that can be easily replaced. Sometimes it's more specialised. Some computers will work fine with a dead battery, other than losing BIOS settings when powered down. Others will do strange things even when they're up and running from the mains power. It rather depends on whether the BIOS/CMOS is solely powered from the battery, or if the battery only takes over when the main supply is off. Power brownouts and spikes can randomise BIOS settings, and the clock. So, if your clock has gone wonky, you may want to check other BIOS settings are sane. Maybe even for a manufacturer's defaults reset, then customise everything, to ensure there's nothing lurking to bug you in another way. Usually, the batteries last a few years. Some last a surprisingly long time. I doubt you'd have to take it to a specialist, unless its really well hidden, or unusual. Do an internet search for CMOS, or BIOS, battery pictures, and you should find enough examples to help you find it. > I am running xfce > the only GUI i can find that might do this is > > > Administration, Add/remove Software, System-Config-Date > but clicking on that is unresponsive Sounds like there may be another problem, then. So far your "internet isn't working" descriptions seemed to only mention the web browser not liking a SSL certificate with a radically different date than your computer. The add/remove software may have a similar problem. I'm still using Fedora 17, and "system-config-date" brings up the older style control configurator for what I'm talking about. Which still should to the job, it shouldn't depend on Gnome, or particular desktops. The "date and time" configurator in the "system settings" control panels probably does, since it's a part of the "gnome-control-center" program. But in what way is it unresponsive? Perhaps a simple "yum install system-config-date" command line approach might be more effective. >> And the second thing that springs to mind regards the clock being way >> off from what you expect: Have you correctly set your computer's >> timezone?

If I were manually setting the time, I'd enter it in local time, taken from a locally trusted time source. Let the computer use the timezone setting to work out the UTC/GMT time difference. It's the calculator, not me. Conversely, if I were going to manually set it to GMT, I'd like to observe something telling me the time in GMT. You may find that once your clock is within a reasonable range from the correct time, that NTP is able to keep it running precisely. Large changes often force a need for manual intervention. -- [tim@localhost ~]$ uname -rsvp Linux 3.8.12-100.fc17.x86_64 #1 SMP Wed May 8 15:36:14 UTC 2013 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
