The CMOS clock is automatically set whenever the system's time is updated. You might want to think about installing NTPD on your NT machine and using NTP to synch instead. rdate can only give you time to the nearest second, and according to http://www.eecis.udel.edu/~ntp/ntpfaq/NTP-s-refclk.htm#AEN4231 , the DCF77 signal is accurate to ~3ms . Precompiled ntpd binaries for NT are available at http://www.ntp.org/links.html -- Dan Nelson dnelson@allantgroup.com
