Using the sun to tell the time

THIS IS A SUNDIAL at Oxburgh Hall in Norfolk . Only useful when the sun shines, which is not always the case in England. According to Wikipedia, that wonderful source of knowledge whose reliability is often good, the earliest known sundials date from 1500 BC. These were discovered by archaeologists working in Egypt. Oxburgh Hall was built largely in the late 15th century.

Five and a half hours ahead of Greenwich Mean Time (GMT): India

INDIA IS A very large country. At its greatest width, it spans almost 1800 miles from east (the Manipur/Bangladesh border) to the west (the western edge of Kutch where it borders Pakistan.). When it is 4 am (GMT) in London, 1500 miles away in Moscow (Russia) and 1800 miles away in Ankara (Turkey), it is 7 am.   Yet, when the sun rises at 4 am in the far east of India, people in Kutch (western Gujarat) will not see the sun rise until 5.30 am. In both places, the clock will show ‘4 am’. This difference arises because all of India (as well as Bangladesh and Sri Lanka) are in the same time zone (Indian Standard Time: ‘IST’). IST is five and a half hours ahead of Greenwich Mean Time (‘GMT’). Incidentally, while researching this piece, I noticed that clocks in Nepal are 5 ¾ hours ahead of GMT.

Some countries spanning many degrees of longitude such as India does, are divided into several time zones (e.g. the USA, the Democratic Republic of the Congo, and Russia). However, all of India is in a single time zone, I wondered why and whose idea it was in the first place.

Prior to the colonisation of India by the British, various methods of standardising time were adopted in different eras and under varying ruling regimes. For example, in the 4th century BC, the prime meridian was chosen as a line passing through what is now the modern town of Ujjain (in Madhya Pradesh) and the unit of time was based on the ‘prana’ (about 4 seconds – the length of a normal breath).

In 1802, John Goldingham, the official astronomer of the British East India Company, established Madras Time, which was 5 hours, 21 minutes and 14 seconds ahead of GMT. In 1884, Calcutta Standard Time was established. This was 5 hours, 53 minutes and 20 seconds ahead of GMT. It remained in use until 1948 despite other changes in time zoning having already occurred in India. At the same time as Calcutta Standard Time was created, Bombay Standard Time also came into existence – it was 4 hours and 51 minutes ahead of GMT. Although it no longer exists, it is still used in Parsi fire temples in Bombay.

Madras Time was used by the railways in British India until the 1st of January 1906, when IST came into existence. It was then that the geographical reference point for time standardisation was moved from Madras to Shankargarh Fort in the district of Allahabad. The reference meridian chosen, 82 degrees and 30 seconds East, was deemed to be the midpoint of India, as it was under British rule. In 1947, when India became independent, IST was kept as the country’s official time. However, both Calcutta Time and Bombay Time remained in use until 1948 and 1955 respectively. The idea of splitting India into two time zones has been mooted, but has yet to happen.

Although IST is the official time in all parts of India, an interesting variation is still in use in the tea gardens in the far east of the country (www.timeanddate.com/time/zone/india). Called ‘Chai Bagan Time (Tea Garden Time), it is one hour ahead of IST (and 6 ½ hours ahead of GMT). It was introduced by British tea companies to increase the number of daylight hours available for working, and is still in use. Using this timing, the sun rises at 5 in the morning instead of at 4 (IST) and sets at about 6 in the evening instead of 5 (IST).

Bombay Time has all but disappeared from use. However, it has been replaced by what some call ‘Bombay timing’, which refers to the habit of people to arrive incredibly late for appointments – especially social engagements. Finally, in a book about Bangalore by Peter Colaco, there is mention of yet another measure of time. There is ‘fie-mint’, which does not mean ‘five minutes’, but does mean ‘not very soon’. For example, he wrote:

“A waiter in a restaurant, once told me our order would take ‘fie-mint’. Did he mean a ‘five minute ‘fie-mint’ or a 30-minute ‘fie-mint’, I asked. He considered the question seriously. ‘Twenty-mint fie-mint’, he clarified.”

It was much earlier than Greenwich Mean Time

DESIGNED BY BENJAMIN Wyatt (1775-1852) and George Louch, then later modified by John Rennie (1761-1821), The Clock House (built 1817) overlooks the harbour in Ramsgate, Kent. As its name suggests, this building is surmounted by a square tower with clocks on each of its four sides. Today, the time on the clocks is Greenwich Mean Time (‘GMT’) or, when appropriate, British Summer Time (GMT+1). But this has not always been the case.

The Clock House was home to chronometers that were used to synchronise shipborne chronometers employed for determining longitude. The edifice stood on what was known as the Ramsgate Meridian Line, which was established in 1819. This was before 1851 when Sir George Airy (1801-1892) defined the position of the prime meridian that runs through the observatory at Greenwich. It was not until 1884 that the prime meridian at Greenwich was recognised internationally, much to the disgust of the French, who hoped it would run through Paris.

The now disused Ramsgate Meridian Line is east of the Greenwich prime meridian. So, when the clocks on the Clock House were set to Ramsgate Mean time, they were 5 minutes and 41 seconds ahead of GMT. A notice beneath the clock tower informs the viewer that the clocks are now set to show the same time as it is in Greenwich. And if there are any ancient mariners still using Ramsgate Mean Time, they are informed by another notice that:

“Ramsgate Mean Time is 5 min 41 sec faster than this clock.”

Whichever time you choose to use, it is well worth spending some hours, if not longer, in Ramsgate, which is full of interesting things to see as well as the Clock House.

A gnomon on the esplanade

FOR THOSE WHO DO NOT know, a gnomon is the part of a sundial that casts a shadow.

The gnomon on the Esplanade at Ventnor

In 1851, Sir Thomas Brisbane (1773-1860), who gave his name to a city in Australia, donated a tall gnomon to the town of Ventnor on the Isle of Wight. In sunny conditions, this object casts a shadow on a line marked on the pavement at noon GMT (1 pm BST). Sir Thomas had spent some time in Ventnor during the mid-19th century, and sadly his daughter Eleanor Australia MakDougall Brisbane died in Ventnor in 1852 at the young age of 29.

As we are discovering during our visit to the Isle of Wight, the sun does not always shine in Ventnor (or anywhere else on the island). Recognising this problem that renders the gnomon useless when the sun is not shining, the town erected a short clock tower near to the gnomon in 1870. This clock was rebuilt in 2001. It bears a plaque commemorating Fred Blake (1924-2001), who, along with his father (Adolphus) and grandfather (James), were: “… proud to maintain this barometer for over 120 years”.

We did not see the gnomon working because of cloudy weather conditions, and the two faces of the clocks displayed different times and neither of them appeared to be working. The barometer seemed to be working. It is curious features such as the gnomon that help make towns on the English coast endlessly fascinating.

Evolution of a shop in North Kensington

I PRACTISED DENTISTRY in North Kensington’s Golborne Road between late 1994 and about 2000. When I first began working there and for a year or so afterwards, the practice faced a double-fronted, old-fashioned fruit and vegetable shop. It was run by the friendly Hicks family.

Later, Hicks closed. Their premises were acquired by their neighbour the Portuguese Lisboa Delicatessen, which continues to flourish today. Lisbon use the former Hicks shop as a warehouse. Whenever I have been able to peer inside the former fruit and veg shop, I have noticed that it’s current users have displayed e little if anything to change its interior appearance.

Hicks is just one of several shops on Golborne Road that have retained aspects of their original facades despite changes of ownership and usage.

Eating afer 9 pm in a village in Essex

WHILE ELTON JOHN was performing in front of thousands in London’s Hyde Park in late June 2022,  a small ensemble was performing works by the baroque composers Pergolesi and Purcell in the large medieval gothic church in Thaxted (Essex). The superbly performed concert in Thaxted starring the Armonico Consort ended well after 9 pm.  This was not a problem for the many well-healed members of the audience in the church, who lived locally and were able to feed themselves in their own homes.

Thaxted, Essex

We could have eaten before the concert, which commenced at 7 pm, but were not hungry before that early hour. The pubs in Thaxted informed us that their kitchens stopped  taking orders for food before 845 or 9 pm.

At a pub called the Star, someone hearing us asking about food after 9 pm, recommended we should head for Farouk’s. The bar attendant and several bystander’s agreed with our informant. The bar attendant kindly said that we could bring food from Farouk  and she would save a table for us at which we could sit and eat after the concert.

Farouk is the owner of a caravan parked in a yard behind a petrol filling station in Thaxted. He and his colleagues,  all from Turkey,  prepare and sell Turkish food in the caravan. And, his eatery closes not at 845 or 9 pm, but at 11 pm.

After hearing superb renderings of Pergolesi’s “Stabat Mater” and Purcell’s “Dido and Aeneas” (semi-staged), we headed for Farouk’s caravan and the Star pub.

While waiting for our food to be prepared at about 9.40 pm, Farouk explained he had come from Gaziantep. He said that in his part of Turkey, which is quite close to Cyprus, Turkish is spoken with an accent that is very similar to that spoken by Cypriot Turks. During the ten minutes it took to prepare our food, Farouk took many food orders over the phone, which goes to show that in Thaxted there is a healthy demand for food after 9 pm.

We enjoyed our food at the table reserved for us at the Star. This welcoming pub is popular with locals. I suspect that its lively clientele was a different segment of Thaxted’s population from that which attended the concert in the church.
