[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)

[edit] Removed piece of information

Another 'false' derivation, from NPL staff, of the MSF callsign is Mac's Standard Frequency, from James 'Mac' Steele the former head of the NPL time group.

I can't locate a claim of this anywhere online easily; please do help out if you know where it can be reliably referenced from. Splash - tk 21:44, 6 April 2007 (UTC)

Better out – little relevance anyway. --Old Moonraker 06:37, 7 April 2007 (UTC)

[edit] Removed comparison with WWVB tx frequency

I removed the bit that said that the frequency of 60kHz is the same as that used by WWVB in the US. It's true, but it could--without further qualification--imply to some readers that clocks/watches for one market will work in the other. The protocols used by the two systems are different, so they are not compatible. --DudeGalea 17:14, 17 May 2007 (UTC)

Well, only if the reader implies such an incorrect interpretation from perfectly correct facts, which happenstance is 'not our problem'. However, the information was essentially ephemera so can happily fade away. Splash - tk 21:29, 18 May 2007 (UTC)

[edit] Reversion of "Unreferenced" etc tags.

This article is adequately referenced, but I am about to add the two specific {{cn}} requests made by the poster of the tag (and replacing a dead link in the process—thanks for that). Complaining that the article is restricted to UK topics is moot, given that it's about a UK government agency, and this tag also removed. Some circular links, i.e. links to this article page, also removed. Please, before going on a tagging spree, register your complaints on the talk page first. You may find that the points have already been taken care of!--Old Moonraker (talk) 10:20, 26 May 2008 (UTC)
