[edit] How do "pips" fit in?
The BBC broadcast the pips on the hour, with five short pips followed by one long pip. This implies that the end of the signal is 000001. When there is a leap-second, there are 6 short pips followed by one long. The article, however, states that a leap second will not be apparent from the signal until the next signal 17 (or 18) seconds later. Can someone clarify this in the article? — PhilHibbs | talk 11:05, 10 May 2006 (UTC)
- Okay, I'm thinking of the Greenwich Time Signal — PhilHibbs | talk 11:07, 10 May 2006 (UTC)
[edit] "Rugby clock"
I've attached a {{cn}}) request to "also known as the Rugby Clock", partly because I've never heard of it (not a good reason – it could be just from general ignorance on my part) and partly because of the timing: it won't be the rugby clock in two weeks' time. If there's no backing I'm thinking of removing it. Observations welcome. --Old Moonraker 08:41, 14 March 2007 (UTC)
- 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"? -- Picapica 21:47, 19 March 2007 (UTC)
- Caught out in general ignorance again! I've reverted the {{cn}} request. The real name will become "The Time From NPL", so it looks like the "time from Cumbria" could be a runner! --Old Moonraker 10:48, 20 March 2007 (UTC)
