Question: Who wrote the poem that is on the clock case in the North Transept of the cathedral that is the seat of the Bishop of Chester?

Context paragraphs:
Time's Paces: Time's Paces is a poem about the apparent speeding up of time as one gets older.  It was written by Henry Twells (1823–1900) and published in his book "Hymns and Other Stray Verses" (1901).  The poem was popularised by Guy Pentreath (1902–1985) in an amended version.  Pentreath saw the poem "Time's Paces" attached to a clock case in the North Transept of Chester Cathedral where it is to be seen today.  Recently the poem was even set to music.  Pentreath quoted his version of the poem in his last sermon at Wrekin College, Shropshire where he was headmaster till 1952.  His version then entered the public domain.  Perhaps he wrote the poem down from memory and reconstructed it in the process.  He may not have consciously intended to improve on Twells' version.

Renaud de Cormont: Renaud de Cormont was a French Gothic Era master-mason and architect who worked on the Cathedral of Notre-Dame in Amiens after his father, Thomas de Cormont, who is believed to have been a disciple of Robert de Luzarches.  There is speculation that Thomas may have been Robert's disciple.  Renaud de Cormont, continued his fathers work on Notre-Dame of Amiens in the 1240s, believed to bring a form of architectural revolution to upper transept and upper choir of Amiens Cathedral through his introduction of a glazed triforium, openwork flyers, and new decorative forms.  Renaud altered the eastern wall of the transept and upper levels of the choir into an ornate glass box held by extremely thin flyers.  This failed monumentally: the triforium had to be replaced, the tracery panels on the flyers crumbled and the transept roses failed.  Of more concern was the fact that the entire eastern half of the building needed to be held up using wooden beams, iron chain, masonry spines and an additional rank of flyers.  Because of this, art historians have likened him to an Icarus whose defective work on the upper transept and choir led to a near disaster, likely a play on the fact that the center of Amines Cathedral contains a labyrinth designed on the floor and his father, or Daedalus in this case, had worked on the cathedral before him.

Wells Cathedral clock: The Wells Cathedral clock is an astronomical clock in the north transept of Wells Cathedral, England.  The clock is one of the group of famous 14th to 16th century astronomical clocks to be found in the West of England.  The surviving mechanism, dated to between 1386 and 1392, was replaced in the 19th century, and was eventually moved to the Science Museum in London, where it continues to operate.  The dial represents the geocentric view of the universe, with sun and moon revolving round a central fixed earth.  It may be unique in showing a philosophical model of the pre-Copernican universe.

James Harrington (1664–1693): James Harrington (1664–1693), lawyer and poet, son of James Harrington of Waltham Abbey, Essex, was educated a Westminster School and Christ Church, Oxford, where he graduated B.A. on 28 May 1687, and took the M.A. degree on 8 May 1690.  He had in the meantime been called to the bar at the Inner Temple, whence he afterwards migrated to Lincoln's Inn.  He rapidly acquired a large practice, being, according to Anthony à Wood, 'much frequented by clients for his wonderful and pregnant knowledge of the common law.'  A career thus brilliantly commenced was cut short by his untimely death, which took place at Lincoln's Inn on 23 Nov. 1693 .  He was buried in the north transept of the cathedral, Christ Church, Oxford.  His death was lamented in some elegant Latin alcaics by his friend, G. Adams (Musæ Anglicanæ, ii.  37).  Harrington was the author of a poem in Latin hexameter verse on the death of Charles II, which displays considerable command of the metre (ib.  ii.  34).  He also wrote:

St Andrew's Church, Bere Ferrers: St Andrew's Church in Bere Ferrers, Devon, England, has the oldest stained-glass window in Devon, excepting Exeter Cathedral; it is 600 years old.  The building was probably built at various times between 1290 and 1340; it is recorded that an archpresbytery was founded here in 1333 and the north transept appears to be the earliest part of the church while the south aisle is the latest, perhaps 15th century.

York Minster astronomical clock: The York Minster astronomical clock was installed in the North Transept of York Minster in 1955.  It was first conceived in 1944 and designed by R d'E Atkinson, chief assistant at the Royal Greenwich Observatory.  The clock is a memorial to the airmen operating from bases in Yorkshire, Durham, and Northumberland who were killed in action during World War II.

Cartel clock: A cartel clock is a cartouche shaped clock designed to hang directly on a wall, very commonly executed in fire-gilt bronze (a.k.a. ormolu).  The form is a more unified development from a wall-mounted bracket clock standing upon its separate, complementary bracket characteristic of the Régence (1715–23), which continued to be stylish in Paris through the 1740s.  In Paris, where the ébéniste's wooden contribution to the case and wall bracket, conceived as complements in design, was by degrees overshadowed by gilt-bronze mounts.  wholly gilt-bronze bracket clock cases became most common by "ca" 1730.  The cartel clock, incorporating clock case and bracket in a single unified organic sculptural conception, was a Rococo invention initiated in Paris.  Highly ornate Rococo examples exist, with flowing, asymmetrical and curvilinear designs, the most notable being a series of unified cartel clocks in half a dozen related models, dateable to the 1730s and 40s and attributed (some of them signed) to Charles Cressent.

Chester Cathedral: Chester Cathedral is a Church of England cathedral and the mother church of the Diocese of Chester.  It is located in the city of Chester, Cheshire, England.  The cathedral (formerly the abbey church of a Benedictine monastery, dedicated to Saint Werburgh) is dedicated to Christ and the Blessed Virgin Mary.  Since 1541 it has been the seat of the Bishop of Chester.

Barometer Clock: Barometer Clock (Boulle) by André-Charles Boulle is a late seventeenth-century French clock created out of ebony, turtle shell, brass, gilt bronze, and enamel.  The clock case is decorated on all sides and was intended as either a centerpiece or for display on a mantel in front of a mirror.  The centerpiece of the clock is a relief of "Father Time Carrying Off Truth."

Thomas Stretch: Thomas Stretch (March 30, 1697 – October 19, 1765) was an American clockmaker and a founder and first Governor of the Colony in Schuylkill, later known as The State in Schuylkill, or Schuylkill Fishing Company.  In 1753 he erected the first clock at Independence Hall in Philadelphia, a large clock dial and masonry clock case at the west end of the structure.
