Updating clock time through terminal

In my Fedora 14 desktop I keep losing minutes without knowing how and why (doesn’t the clock update automatically?). At the beginning I tried to change the file /etc/ntp.conf (edit it and change the parameter server to: ‘server pool.ntp.org’; 1) as perhaps the server did not respond correctly.

Of course this does not come without any troubles but, thankfully, all have been solved quicker than expected. The first and more serious problem was to install the necessary drivers for the graphics (an […]
