What is the "right" time, especially in a world in which "time" is adjusted according to the seasons?
Here in Britain, until the 1840s and the development of the railways (and the need for timetables), each town or city kept its own time, which differed, sometimes by ten or more minutes, from the time kept elsewhere, and particularly "London Time", as set by Greenwich. Even after railway clocks were synchronised with Greenwich Mean Time, many towns refused, sometimes for decades, to alter their other public clocks, their residents presumably developing mental clocks which recalculated time if they needed to catch a train or keep an appointment in town. To this day, a type of "Oxford Time" still exists, thanks to the clock on Tom Tower, still stubbornly and quaintly five minutes ahead of the rest of the country. A few other clocks in Oxford also ring out different times; thus I soon learnt to recognise peals and knew without needing to check my watch how fast or slow each one was.
But in fact, while I lived there my own home was a microcosm of Oxford's many clocks, though rarely in synch with any one in particular! What, exactly, is "standard time" or even the "correct" time, when laptop, phone, alarm, cooker, microwave, tablet and God knows what else each manage to differ from each other, sometimes by a few minutes? And when these differ from my watch and car clock? Yes, I could of course have synchronised everything with Big Ben, but modern appliances are rarely straightforward, and all this would be time-consuming. Much easier to do as those Victorians did, and simply get used to remembering by how much each device is fast or slow, and make my mental adjustments accordingly.
Which is why, for the next six months, I will be driving a car whose clock is 54 minutes faster than my watch - as I have every winter since I inherited it in 2012! Why waste precious time frowning and fiddling with a clock I'll only have to re-fiddle with in March, and which I already know is 54 minutes fast? No, like so many others, I save my time, preferring to spend half the year with a clock which is an hour or so astray...
