My clock moves up an hour every day and I have to change it every morning. Does anyone know what would cause this and a way to fix it?
If you don't change it, will the clock be off by two hours the next day (and three hours the next...)? Or will it still only be off by one hour?
As to why...
Your computer's hardware clock does not keep track of time zones or whether Daylight Savings Time is active. These things are handled in software.
When you boot your system, Fedora will load the time that is stored in the hardware clock and then adjust it for your time zone and for DST (if necessary). When you shutdown your computer, it should write the time to the hardware (again adjusting for TZ and DST, but in the other direction).
There are basically two options with regard to timezone adjustment. The hardware clock is set to your local time, or it is set to UTC (Coordinated Universal Time). If you use more than one operating system on your computer then they should all be set to the same option, otherwise the OSes will be setting the hardware clock using different adjustments. Microsoft's OSes are not capable of supporting the UTC option*, and so to avoid problems when dual-booting Windows you should configure your GNU/Linux OS to use your local timezone.
If your computer is always connected to the Internet, you should enable NTP (Network Time Protocol) so that your computer's hardware clock is basically ignored and your OS gets its time from a time server (and keeps it in sync with periodic updates).
Could you please post the contents of the file
/etc/adjtime?
* [edit] Correction. Windows can handle UTC as long as you go in and edit its Registry manually.
