The Time Ball on the Nelson Monument (Calton Hill*) http://www.ewht.org.uk/GetFile.aspx?ItemId=478
is also currently undergoing repair, and should soon be back in action, along with the One O'Clock Gun which is fired from the castle daily:http://www.ewht.org.uk/Work-starts-at-the-Nelson-Monument.aspxhttp://www.ewht.org.uk/Time-ball-connection-with-pioneer-Victorian-inventor.aspx
The connection? Greenwich and its time ball:http://www.nmm.ac.uk/explore/astronomy-and-time/time-facts/the-greenwich-time-ball
Greenwich is, of course, itself a WHS.http://www.greenwichwhs.org.uk/http://www.flickr.com/photos/travelbug60/sets/72157607339812205/
What time does the time-ball drop at Greenwich?
In 1833 a red "Time Ball" was installed on the roof of the Royal Observatory Greenwich
Daily at 1pm a red time ball drops on the Old Observatory to set World Time
It drops at 1pm because the astronomers were busy with their telescopes with the midday sun.
At Greenwich the bright orange time-ball on the observatory roof drops at 1pm every day. It has done this every day since 1833. 1pm was originally chosen to enable the astronomers to undertake telescopic observations at noon. The tradition is maintained today for the benefit of tourists. NB In summer it drops at 13:00 (1pm) BST or 12:00 (Noon) GMT."http://wwp.greenwichmeantime.com/info/timeball.htmhttp://www.worldheritagesite.org/sites/maritimegreenwich.html

In itself, Calton Hill is considered a WHS 'connection':
"UNESCO World Heritage site of Edinburgh. This site, designated in
1995 encompasses the Old Town, which is dominated by its medieval fortress; and the
neoclassical New Town, whose development from the eighteenth century onwards had a far-reaching influence on European urban planning. These two contrasting historic areas, each with many important buildings, is what UNESCO states "gives the city its unique character and outstanding universal value."
In between these two areas, however, at the eastern end of the World Heritage Site, lies what is considered as the link
between these juxtaposing areas. This is a small protrusion of volcanic rock known as Calton Hill, which is considered as a significant example of a nineteenth century designed landscape by William H. Playfair. This area is particularly important within a Scottish context but is also significant within the wider scope of architecture and planning during the nineteenth century, particularly as it is centrally situated within a bustling mercurial urban environment, yet has remained by-and-large as it was originally planned."
