The Royal Observatory, Greenwich is an observatory situated on a hill in Greenwich Park in south east London, overlooking the River Thames to the north. It played a major role in the history of astronomy and navigation, and because the Prime Meridian passed through it, it gave its name to Greenwich Mean Time, the precursor to today's Coordinated Universal Time (UTC). The ROG has the IAU observatory code of 000, the first in the list. ROG, the National Maritime Museum, the Queen's House and the clipper ship Cutty Sark are collectively designated Royal Museums Greenwich.
A time signal is a visible, audible, mechanical, or electronic signal used as a reference to determine the time of day.
Standard time is the synchronization of clocks within a geographical region to a single time standard, rather than a local mean time standard. Generally, standard time agrees with the local mean time at some meridian that passes through the region, often near the centre of the region. Historically, standard time was established during the 19th century to aid weather forecasting and train travel. Applied globally in the 20th century, the geographical regions became time zones. The standard time in each time zone has come to be defined as an offset from Universal Time. A further offset is applied for part of the year in regions with daylight saving time.

The Shepherd Gate Clock is mounted on the wall outside the gate of the Royal Observatory, Greenwich building in Greenwich, Greater London. The clock, an early example of an electrically connected clock system, was a sympathetic clock mechanism controlled by electric pulses transmitted by a motor clock inside the main building. The network of 'sympathetic clocks' was constructed and installed by Charles Shepherd in 1852. The clock by the gate was probably the first to display Greenwich Mean Time to the public, and is unusual in using the 24-hour analog dial. Also, it originally showed astronomical time which started at 12 noon, not midnight.

The Chief Post Office or Christchurch Central Post Office, originally known as the Government Buildings, is located in Cathedral Square, Christchurch, New Zealand. The building was initially a post office with Immigration, Customs and Public Works departments. The Government Buildings were later replaced by the new Government Buildings opened in 1913, and the Chief Post Office remained on-site. In 1881, New Zealand’s first telephone exchange was installed in the building. Post services were offered from the building until 2000 when it was re-purposed to house a Christchurch tourist information centre and a restaurant, café and offices. Following the 2011 Christchurch earthquake the building closed. In the early 2020s repairs and strengthening took place. The building is planned to reopen in 2023 in stages, and will eventually include a restaurant, shops, and a visitor information centre, under the name "The Grand". The structure is registered with Heritage New Zealand as a Category I heritage building.
