"By tinkering with the clock, physicists at the National Physical Laboratory (NPL) near London, led by Dr Krzysztof Szymaniec, were able to reduce its margin of error to unprecedented levels."
Pretty much tells you where the clock is, and legally speaking that's the "right" time for the UK so I guess that the telecoms systems will listen to it. However there are no telecoms systems that need a clock that good- if there were then they wouldn't work.
Also, it's not that they know that it loses a zillionth of a second a day ( which they could compensate for) but that they know that it loses or gains no more than that error, but they don't know how much less or whether it's fast or slow because they don't have a better clock to compare it against.
