Nothing sexy here, but in response to some serious confusion on the NTP 
mailing list, I put together some plots of the 1pps output from a 
Motorola M12+ Timing Oncore versus an Rb standard.  It may be helpful if 
you want to point people to info about GPS timing capabilities.

(Some folks on comp.protocols.ntp were busy lawyering the Motorola 
manual and getting really screwed up about the accuracy -- or lack 
thereof -- of the 1pps signal.)
