:The phrase "Rugby clock" IS used to refer to the NPL time signal. See:  
 ::"...use the information to decode the signal from the Rugby Clock, and display hours and minutes on the LED Clock Display" (From a University of Cambridge Computer Laboratory study assignment)  
 ::"Observers making visual observations in the main referenced their timings directly to the Rugby clock." (Observational report on the 08.06.2004 transit of Venus) 
 :But it's true that such users will have to change the name come 01.04.2007  to the "Cumbria Clock"?
