DateFM syncs computer clock time by using FM radio signals, ensuring accurate timekeeping.
The process is simple: DateFM scans the actual date from FM and sends it through RS232 to your PC. It then checks the format, compares the date from your PC with the one from RS, and changes the ticking of the clock inside your PC to the correct time.
To use DateFM, you must have packet "adjtimex" to manipulate your kernel and synchronize your system clock. It's also important to remove the file "last.txt" while rebooting your system to get a more accurate calculation of how wrong your system clock goes.
Additionally, you'll need to meet some requirements, including adjtimex, datefm.conf, and restore.stty. If you want to install the packet, just edit the datefm.conf file to configure the parameters.
DateFM reads on the serial line, calculates how your system clock goes, updates CMOS, and corrects your system clock in the kernel. Last gets the time from file "last.txt" (if it exists) and displays how many times ago the first update from FM happened.
The latest release of DateFM has some exciting new features, including the ability to get options of ttySX before synchronization and restore them afterward. It also includes a file restore.tty for easier configuration and a configure script. Plus, it's no longer bundled with adjtimex, so you can obtain it from an FTP server.
Say goodbye to inaccurate computer clocks and hello to DateFM.
