But why would one want to when ntpd is so easy to use and has the advantage of tuning the kernel's clock for even more accurate time keeping? Put this in your /etc/ntp.conf to save ntp's kernel PLL tweaks between reboots: # Write clock drift parameters to a file. This will allow your system # clock to quickly sychronize to the true time on restart. driftfile /etc/ntp.drift -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
