Grandad encourages me to wind it up, as he had done before. My 21st century hands, accustomed to the convenience of the automated digital time of my iPhone lock-screen, don\u2019t feel worthy of the venerable device. <\/p>\n<p class=\"c-paragraph paywall \">Embarrassingly, I\u2019m not sure whether to turn the stem winder clockwise or anticlockwise, so I try both. Much to my delight, the dormant timepiece\u2019s second hand comes to life, and the steady ticks of its mechanical heartbeat start to measure the passage of time once more. <\/p>\n<p class=\"c-paragraph paywall \">Grandad recalls how his grandfather proudly donned this portable timepiece during a rather unusual period for Irish timekeeping. The Statutes (Definition of Time) Act 1880 established Dublin Mean Time (DMT) as Ireland\u2019s national standard time. <\/p>\n<p class=\"c-paragraph paywall \">Prior to 1880, each town operated on local mean solar time, with noon occurring when the sun reached its highest point in the sky at a given location, such that the time that people observed reflected the local environment rather than a distinct standard. <\/p>\n<p class=\"c-paragraph paywall \">DMT was based on the local mean time recorded at Dunsink Observatory, just northwest of <a href=\"https:\/\/www.irishtimes.com\/tags\/dublin\/\" target=\"_blank\" rel=\"noreferrer nofollow noopener\" title=\"https:\/\/www.irishtimes.com\/tags\/dublin\/\">Dublin<\/a> city. Dunsink\u2019s location being a little over six degrees west of Royal Observatory Greenwich meant that DMT was 25 minutes and 21 seconds behind Greenwich Mean Time (GMT), the official time in Great Britain. <\/p>\n<p class=\"c-paragraph paywall \">Over the 36-year lifespan of Ireland\u2019s unique time zone, this distinction came to be seen as an administrative inconvenience in an increasingly interconnected world. This was particularly evident in Ireland\u2019s transport and communication systems. <\/p>\n<p class=\"c-paragraph paywall \">Mailboats from Holyhead in Wales used to arrive at Kingstown (now <a href=\"https:\/\/www.irishtimes.com\/tags\/dun-laoghaire\/\" target=\"_blank\" rel=\"noreferrer nofollow noopener\" title=\"https:\/\/www.irishtimes.com\/tags\/dun-laoghaire\/\">D\u00fan Laoghaire<\/a>) harbour to be met by the Dublin and Kingstown railway line, which Grandad recalls extending right out on to the pier to collect passengers and parcels headed for Dublin. <\/p>\n<p class=\"c-paragraph paywall \">The accuracy and co-ordination required for such meticulous operations encouraged the introduction of the Time (Ireland) Act 1916. But Irish nationalists interpreted it differently. To them, abandoning DMT and synchronising Irish and British time zones symbolised a loss of Irish identity, which was especially important at such a pivotal time in Ireland\u2019s push for independence. <\/p>\n<p class=\"c-paragraph paywall \">So while GMT was observed by the banks and post offices, it was rejected by much of the Irish population, who tenaciously stuck with Dublin Mean Time, or, as some locals liked to call it, Old God\u2019s Time. <\/p>\n<p class=\"c-paragraph paywall \">From 1865 until 1916, the famous Time Ball on top of the Ballast Office (then headquarters of Dublin Port) at Aston Quay dropped every day at 1pm to allow navigators on ships in the Liffey to calibrate their chronometers. <\/p>\n<p class=\"c-paragraph paywall \">The dropping of the Time Ball started to follow GMT around 1914, a couple of years prior to the official switch, but locals knew that the descent of this giant bronze ball down its mast indicated a local time of 12.35pm, as deliberated by Leopold Bloom in James Joyce\u2019s Bloomsday. <\/p>\n<p class=\"c-paragraph paywall \">Meanwhile in Tullow, my great-great-grandfather\u2019s hometown in <a href=\"https:\/\/www.irishtimes.com\/tags\/carlow\/\" target=\"_blank\" rel=\"noreferrer nofollow noopener\" title=\"https:\/\/www.irishtimes.com\/tags\/carlow\/\">Co Carlow<\/a>, there was no such sophisticated community timepiece. And so possession of a personal timepiece conferred considerable social status. <\/p>\n<p class=\"c-paragraph paywall \">One could estimate the approximate time based on when the church bells last chimed, or even the apparent position of the sun in the sky. But only the gentleman with a silver chain peeking out from his waistcoat might know the right time.<\/p>\n<p class=\"c-paragraph b-it-article-body__interstitial-link\">[\u00a0<a aria-label=\"Open related story\" class=\"c-link\" href=\"https:\/\/www.irishtimes.com\/culture\/heritage\/a-brief-history-of-irish-time-1.1572097\" rel=\"noreferrer nofollow noopener\" target=\"_blank\">A brief history of (Irish) timeOpens in new window<\/a>\u00a0]<\/p>\n<p class=\"c-paragraph paywall \">For most people, however, daily tasks could be scheduled around more general periods like morning and evening, and the precision of minutes and seconds hadn\u2019t yet become central to the daily routines of Irish lives. <\/p>\n<p class=\"c-paragraph paywall \">I remind Grandad of his witty narrative about how the Carlow farmers would claim that their cows didn\u2019t know anything about GMT, but followed a time determined by the sun. As Grandad says, perhaps it was the cows who knew the right time. <\/p>\n<p class=\"c-paragraph paywall \">I place the tireless old pocket watch on Grandad\u2019s desk, alongside my iPhone and Grandad\u2019s laptop. I wonder what my great-great-grandfather would think of the modern timepieces of his descendants and how they compare to his own. Would he marvel at the efficiency and accessibility of the smartphone and the precision of the atomic clock to which it is synced? <\/p>\n<p class=\"c-paragraph paywall \">In humanity\u2019s pursuit of the right time, our modern technologies have achieved a level of accuracy far beyond what can be perceived in everyday life. To tell the time, we no longer need to approach strangers on the street or seek out the local timepiece, nor must we take part in the daily ritual of winding up our watches to ensure their reliability. We have traded the social and tangible aspects of timekeeping for precision and convenience. <\/p>\n<p class=\"c-paragraph paywall \">As we continue to venture deeper into our modern obsession with precise timekeeping, it is worth considering how our relationship with time has been transformed by this obsession. <\/p>\n<p class=\"c-paragraph paywall \">On my morning commute to college (as a medical student on clinical placement in the Coombe Hospital), I cycle past St Patrick\u2019s Cathedral, home to Dublin\u2019s oldest public clock, which dates back to 1560. I often steal a glance over my left shoulder at the old clock atop the cathedral\u2019s impressive tower, knowing that the closer its minute hand is to pointing straight upwards to the XII numeral, the faster I should pedal in order to get to the Coombe on time. <\/p>\n<p class=\"c-paragraph paywall \">Inevitably, I am always rushing \u2013 my parents say that I have no concept of time. But concept of time has changed, and I can\u2019t help but envy the students of years gone by, for whom a matter of seconds and minutes probably carried far less weight. <\/p>\n<p class=\"c-paragraph paywall \">I somehow also envy those old cows of Carlow, who, despite the temporal frenzy around them, always seemed to know what time it really was. <\/p>\n<p class=\"c-paragraph paywall \">Taking part in creative writing as a medical student<\/p>\n<p class=\"c-paragraph paywall \">Cian Morgan\u2019s story was inspired by the recollections of his grandad, BJ Nangle, and won the top prize in this year\u2019s Mary Mulvihill Award for science media.<\/p>\n<p class=\"c-paragraph paywall \">The competition, which is in its 10th year, is held in honour of the late scientist, writer and author, Mary Mulvihill, who died in 2015.<\/p>\n<p class=\"c-paragraph paywall \">Morgan is a medical student at <a href=\"https:\/\/www.irishtimes.com\/tags\/trinity-college-dublin-tcd\/\" target=\"_blank\" rel=\"noreferrer nofollow noopener\" title=\"https:\/\/www.irishtimes.com\/tags\/trinity-college-dublin-tcd\/\">Trinity College Dublin<\/a> where creative writing is part of the Medical Humanities module. He explains here why creativity and hard sciences complement each other.<\/p>\n<p class=\"c-paragraph paywall \">In the 21st century, where access to knowledge seems to be unlimited, science is becoming less about the pursuit of information about the world, and more about critically analysing this information and developing new ideas. <\/p>\n<p class=\"c-paragraph paywall \">Being critical and innovative requires traits such as creativity, imagination and, most importantly, curiosity. <\/p>\n<p class=\"c-paragraph paywall \">As the field of medicine becomes increasingly technology-driven, integrating these traits into medical education can help medical students develop skills that artificial intelligence can neither replicate nor replace. <\/p>\n<p class=\"c-paragraph paywall \">The school of medicine in Trinity College Dublin has begun to focus on these less academic aspects of medical education with the idea of developing well-rounded doctors. <\/p>\n<p class=\"c-paragraph paywall \">For example, in year one of our curriculum, we take part in a Medical Humanities module \u2013 which, in my case, involved creative writing \u2013 to deepen students\u2019 understanding of the human experience of illness. <\/p>\n<p class=\"c-paragraph paywall \">Similarly, the annual Mary Mulvihill Award encourages tertiary level students to explore new perspectives and to appreciate the role of storytelling in science. It is very fitting that Mary Mulvihill should have this legacy, considering her inquisitive nature and unwavering commitment to science communication. <\/p>\n","protected":false},"excerpt":{"rendered":"On entering his office, Grandad reaches to the top shelf to fetch his box of memorabilia, his personal&hellip;\n","protected":false},"author":2,"featured_media":606060,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[16665,16089,61,60,256876,43,2055,15342],"class_list":["post-606059","post","type-post","status-publish","format-standard","has-post-thumbnail","category-ireland","tag-carlow","tag-dun-laoghaire","tag-ie","tag-ireland","tag-leopold-bloom","tag-news","tag-students","tag-trinity-college-dublin-tcd"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/606059","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=606059"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/606059\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/606060"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=606059"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=606059"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=606059"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
