A sundial gives in principal an indication of the local time. The sun travels across the sky at the rate of fifteen degrees per hour so every degree of longitude represents a difference of four minutes from the standard meridian for the region.

It is his hobby
Reid Cowan is becoming an expert on Timaru's sundials. But there's one that's refusing to give up its secrets, and the retired surveyor is hoping someone will be able to offer assistance. Mr Cowan has been involved in the removal, restoration and relocation of a number of Timaru's sundials, and that's led him to preparing a guide to understanding them. He wants to include information on the six sundials in schools and public places in and around Timaru, and while he's been able to find out about most of them, one has him stumped. The sundial at Waimataitai School was engraved in 1933, and with the school holding a jubilee a year earlier, it would seem likely it was a jubilee project. However, an extensive trawl through school minutes has revealed no mention of it, and neither has a search of Timaru Herald files. Mr Cowan's now wondering whether it was donated from a private garden in Timaru, but he'd welcome any clues as to its history. Most of Timaru's sundials have had the benefit of Mr Cowan's experience in recent years. The Timaru Main School jubilee sundial is to be re-erected at Bluestone School, while Claremont School's sundial will find a new home at Barton Rural (formerly Fairview). Mr Cowan was also involved in repairs and relocation of Craighead School's sundial, dedicated to the memory of the school's first principal, and the Robert Heaton Rhodes sundial - first erected at the end of The Terrace, then moved to Caroline Bay, above the Soundshell seating when the Port Loop Road was constructed. It's now likely to get a third home once decisions are made on where it should be placed. Caroline Bay also boasts the Victoria Cross Memorial Sundial, installed by the Caroline Bay Association in memory of those awarded the Victoria Cross. He finds it fascinating that most were put in place at great expense when there wasn't much money around. "They were put there in the 1930s, in the depression years when things were grim, so they have to be preserved, they can't be just dumped, they have to be looked after." One hundred copies of the booklet have been produced, and distributed to schools and libraries. Mr Cowan's main ambition is to see children in the district able to read sundials at their school, or even make their own.
A test of time: After about five years of working with sundials, Timaru's Reid Cowan knows his shadows, latitudes and longitudes.

thy time wisely. History of sundial less of a mystery
Timaru Herald, Oct 1, 2005
Reid Cowan's search for the story of Waimataitai School's sundial has had some success. The retired surveyor this week asked for help in finding out the history of the feature. While he'd been able to research the five others in schools and public places around Timaru, there didn't seem to be a shred of information available about how Waimataitai School came by its sundial. However, following Thursday's story, Mr Cowan received a phone call from Don Lithgow, whose family owned land around the school. Mr Lithgow said he could remember his grandfather John Lithgow telling him he had given a sundial to Waimataitai School.
There are two sundials on the bay.
Caroline Bay Victoria Cross Memorial and Sundial was installed by the Caroline Bay Association in memory to New Zealand's eleven recipients of the Victoria Cross. If you walk around Caroline Bay, Timaru you will see the lengthy knee-high, 350 metre, Memorial Wall built in 1929 that list the names of the 101 battles New Zealanders fought in during WW1 on locally made bronze plaques. It also marks the line where land and sea once met. Finished in plaster and Moeraki shingle, the cost was £616 10s 11d. The sundial is in the centre of the wall at the new World War I interpretive memorial. The sundial cost £117 8s 0d . There is a plaque on the front of the memorial listing the names of the Victoria Cross recipients. This is Timaru's most prominent sundial and was the work of James Stewart of Invercargill. Sundials were his hobby. Stewart was apprenticed in the whitesmithing and brass-finishing trade. In his advancing years he maintained his sundial construction, developing a reputation that had clearly been enhanced by his display in the New Zealand and South Seas Exhibition in Dunedin 1925-26. He has been credited with approximately 200 dials throughout New Zealand, Australia and Britain. On 11th November 2009 at 11 am the new World War interpretive memorial on Caroline Bay was unveiled and incorporated the old sundial. The interpretive memorial will give meaning and understanding to the 99 balls on the 80-year-old memorial walk, South Canterbury War Memorial Society chairman Mark Hervey said. There is now a 35 minute longitude correction plaque, 4th photo.

Horas non numero nisi serenas I don't count the hours unless they're tranquil. Both sundials on Caroline Bay have the same motto. This one is near the paddling pool at the top end of the bay and is probably the first sundial in Timaru. Surrounding the other sundial for VC heros is updated War Memorial.
Sundials also can be found in private gardens and at:

William Geddes was a prominent citizen of Waimate and is remembered through this sundial in Victoria Park installed after his death in 1932. It was presented to the borough of Waimate on September 21, 1934. The engineering firm is John Swan and Co., Dunedin. The company has been in business since 1878.
“The foothills empurpled in gleaming,
Mt Studholm in sunset aglow,
Waimate my heart turns while roaming,
To the best little town that I know”.
This memorial is placed here by friends and
admirers of William Geddes, J.P.
Born Scotland 1851, died Waimate 1932
He found joy in service!
While this sundial measures the flight of time,
it records that William Geddes, J.P. served Waimate
in very many ways, though long years,
and notably as chairman of the
Waimate Hospital Committee for seventeen
years, and as a member of the S.C. hospital Board.
After seventy years experience,
and a tour of the world,
Mr Geddes acclaimed Waimate as
"the best little town that I know."

Another sundial in the planning
By Matthew Littlewood - The Timaru Herald 16/07/2010
Stargazing and astronomy tour operator Freidl Hale wants to build an interplanetary sundial near the Lake Tekapo domain. Ms Hale, along with a steering committee, has been working towards the project, and just this week they discovered they had received a $15,000 grant from the Meridian-Waitaki community fund. Once completed, the sundial will be located in the Lake Tekapo domain. Ms Hale said it was part of a much bigger project, with the intention to produce two separate scale models of the solar system. "The small model will be entirely contained in the Lake Tekapo Domain, and will just be a neat way to get people to learn about the stars and planets," she said. "It will be to scale, so you could be sitting out by Jupiter as you have a coffee near the Church of the Good Shepherd." Ms Hale said the larger model solar system would stretch right throughout the Mackenzie. "It would be to scale, so for example, Pluto, which would be located near Lake Benmore Dam, would be very small – about 1cm – but Jupiter, which will be near the shore of Lake McGregor, would be about 1.3m in diameter. It would give people an idea of the size of our solar system, and our relationship to it. Each model will always be a work in progress as scientists discover more about our neighbourhood in space." The group estimates the project will cost about $60,000 all up, and hopes to start construction later this year.
You don't want sundials to be bright and shiny. They should cast a shadow, not a reflection.

feature sundials, about five in NZ. e.g.
There are two sundials in the Christchurch Botanic Gardens and one with a limestone pedestal near the fernery at Mona Vale.

Nov. 15 2009. Location: Southern hemisphere: Sydney, Australia. The hour numbers are counting down to the right. Armillary sphere sundial, Herb Garden, Royal Botanic Gardens Sydney, 1993, This sundial has to mimic the earth and its position to the sun in order to show us the right time. That means the gnomon, the arrow, that runs through the centre of the sundial has to point in exactly the same direction as the north/south axis about which our earth rotates. The ring supporting the hour markings, represents the equator.

Message of the sundial
|Time flies, and flowers fade;
new days, new ways; love stays.
|I give warning how the hours fly,
For men are shadows, and a shadow I.
|Give light to them that sit in darkness,
and guide our feet into the way of peace.
|Only be thou strong and very courageous||Time is swift-much is to be done.||I count only happy hours|
|Smiles equal sunshine in helping folks along||Serene I stand amidst the flowers
To tell the passing of the hours
|Do like a sundial and count only the sunny hours!|
|Watch and Pray
Time flies away
|Set me right and use me well,
Then I the time to you will tell.
|Horas non numero nisi serenas
I don't count the hours unless they're tranquil.
|Light is the shadow of God||Let others tell of storms and showers, I'll only count the sunny hours.||I take no note of time but when the sun is shining|
Time can be measured by shade.
The measurement of time has become of increasing importance to man with the advance of civilisation. At first it was based on the succession of night and day, the waxing and waning of the moon and on the changing seasons of the year. The clock was developed for dividing the day into smaller units and adjusted to keep in step with the rotation of the earth. The earliest timekeeper was a shadow clock, a primitive form of the sundial. In a sundial the vertical stake was replaced by a style inclined, according to latitude, till it lay parallel with the earth's axis, and the shadow then moved evenly throughout the hours of daylight. A dial face and style is all that is needed on a sundial face everything else on the plate is furniture, not necessary. Most sundials are constructed for a specific place. The horizontal dial measures the hour angle of the sun from the meridian. Noon is the meridian hour. For a sundial to work the dial plate must be flat, the twelve o'clock line must be due south and north. The gnomon (the g is silent) (style), set to the correct latitude, has to point to the true South in the southern hemisphere and also the hour numbers on a horizontal dial run anti-clockwise rather than clockwise. Face the sundial due south. A horizontal sundial is impractical on the equator and L equals 0 degrees, the style would be flat and cast no shadow. At the South Pole L would be 90 degrees. There are websites with free shareware for working out the dial plate but is it correct? Here is the one I tried for Timaru, it was easy to do. A sundial designed for one latitude can be used in another latitude, provided that the sundial is tilted upwards or downwards by an angle equal to the difference in latitude. For example, a sundial designed for a latitude of 40° can be used at a latitude of 45°, if the sundial plane is tilted upwards by 5°, thus aligning the style with the Earth's rotational axis. In the southern hemisphere sun-cast shadows turn anticlockwise through the day and sundials have the hours increasing in the anticlockwise direction. Hurricanes and tropical storms spin clockwise in the southern hemisphere (as opposed to anticlockwise in the Northern Hemisphere) due to the Coriolis effect.
The 45th parallel is the midway point between the equator and the South Pole. A marker is located on SH1 north of Oamaru and just south of Hilderthorpe and there is another monument marking the 45 degree line of latitude on the Te Anau - Milford Rd and another marker at the 45th Parallel marker just north of Lowburn on SH6 on the bank of Lake Dunstan, a few km N. of Cromwell.

Finding True North
To determine True North is a simple matter by using the daily paper details of Timaru tides, sun and moon. For example, on June 10 the sun rises at 8.06 am and sets at 5.03 pm. From these figures the sun is in the sky for eight hours, 57 minutes, let us say nine hours. Halve the nine hours and add to sunrise and we can easily determine that the sun is at maximum altitude and True North at approximately 12.36pm. The sunny shadow from a stick placed vertically in the ground, the corner of a building, or the shadow east across a living room floor allows one to easily determine True North. Magnetic North, as shown by a compass, is not nearly as good as the simple method I describe. Magnetic North is approximately 23 degrees to the east of True North in our area and a compass is more difficult to handle. A local newspaper, a little arithmetic and a sunny day is all that is required. Reid Cowan, Timaru. June 9 2015 Timaru Herald

THE SUNDIAL.by R. S. H.
In a garden, lone and wild.
An old sundial stands ;
In that garden when a child
I have often played, and smiled
I see the shadow grow so long,
While the bells at evensong
Chimed the dying day,
Seeming soft to say,
"Time passes away. "
In that garden, lone and wild,
Now I sit and think
Of the time when, as a child,
Innocent and undefiled,
I played there, and a silent tear
Steals adown my cheek, so near
Seems that time — now far away :
And the church bells seem to say,
" Ah ! that time has passed away."
Yes, the years have fleeted fast
Since that happy time ;
Many friends to death have passed,
I alone am left, the last
Of that merry band,
By the sundial old I stand,
While as dies the day
The solemn church bells seem to say.
" Soon, you too must pass a way."
