Hi Ken,

The ATOM driver is not considered until the system clock has been
steered within 0.4s of the PPS signal.  To troubleshoot, you could
install debug ntpd.exe and invoke it from a command prompt, adding -n
-D3 or similar to the command-line options to run interactively and
enable debugging output.

Good luck,
Dave Hart
