The twinge of guilt we feel when we are only late by two minutes. The hasty apology sent while we are still on the bus. The persistent self-reproach of someone who is 7 minutes late to a coffee meeting with another, and spends the first 3 minutes berating himself as though his lateness was a window into his soul. We treat punctuality as if it were a virtue on a par with honesty or keeping one’s word. And it’s not. Punctuality is a Victorian logistical problem that sank quietly into the national consciousness somewhere around the 1840s.
Bristol Was Running Ten Minutes Slow (And Nobody Cared)
In Britain, before the arrival of the railways, each town was on its own local time, set by the peak solar time for that place on the Earth. Bristol would be about 10 minutes slow on London time, and Exeter about 14 minutes slow on Greenwich time. There was no particular problem with this as the normal uncertainty of travel would already account for a day either way on a journey, by coach for example. The difference between Bristol time and Greenwich time would have been of little more account than a weather forecast.

"Late" had already been a word which described things delayed by circumstance and not the people who were late. Time was approximate because it had to be, and being approximate was not a moral failing.
The Problem the Timetables Couldn't Ignore
The railways introduced a new requirement: the whole country had to operate with a single shared clock. Trains running between London and Bristol could not be ‘approximately on time’. If a train was due at Bristol Temple Meads at 14:30 and the local time differed from the London time by ten minutes, then arriving trains would not be expected and there could be serious consequences including the risk of a collision on a single-track line. The Great Western Railway started running on London time in 1840 and by 1847 most other companies had adopted GMT as their standard time. It was not until 1880 that it became law.
This is the hinge. The railway companies needed operational precision, so they imposed a universal minute on the whole country. And once you have a shared minute, "late" becomes a measurable, objective fact rather than a meteorological shrug.
The Diary Was Not a Human Instinct
All of these other things follow from the shared clock having been established: the fixed workday with the set start time, dinner parties with times printed on the invitation (e.g. “7:30 for 8”), the school bell, the reviews held at set times on a quarterly basis. None of it works without a universal standard; it all stems from a Victorian infrastructure project, not deep human instinct.
And then we internalised the schedule and the moral implications of being late. Punctuality became another way to judge our character as we choose to arrive on time or not. It was an engineering requirement that slipped unnoticed into character assessment.
This can be read about in more detail, including how repeated choices become identity, in Every Time You Do Something, You're Voting.
Consider the latecomer. His visible phone check, exhaled apology and brief explanation for his delay aren't really about the seven minutes. Rather, they serve to prove that he is indeed a member of this community who shares its moral code and knows he has temporarily transgressed against it. A Victorian railway engineer could find much to satisfy him in such a display.

Did any towns actually resist Greenwich time?
Oxford famously kept its own local time on the Christ Church Cathedral clock – five minutes behind GMT – until well into the 1880s. Whether that was principled stubbornness or just not getting round to it is a matter of some debate.
Was there any concept of punctuality before the railways at all?
Yes, but time was organised differently before. Instead of one clock ticking away, churches ringing their bells for services, markets opening at certain times and military musters held to the beating of drums organised people's lives. Being late for a market meant that you missed the market. Being late in the modern sense of guilty, apologetic and measurably behind a shared minute of time came with the arrival of the railway timetable.
Does knowing any of this mean it's fine to be late?
Not particularly. Shared time is still necessary for the coordination of millions of people, and by formalising it as a social agreement it transfers the virtue of being on time from a natural human quality to a useful arrangement, which is a slightly more honest place for it.
FAQ
Why did Britain adopt a single standard time?
The growth of railways across the country made it necessary for trains travelling between towns to operate on the same time. As each town had its own local time, the threat of collisions on single-track lines, amongst other problems, was real. The Great Western Railway switched to London time in 1840, with most other companies switching to GMT by 1847.
When did Greenwich Mean Time become law in Britain?
From 1880 GMT (Greenwich Mean Time) became the legal time for the country. The Great Western Railway had been using London time since 1840 and by 1847 most other companies had adopted GMT. The change to GMT had occurred decades before it became law.
How far off were local times before the railways?
Local time was determined by the sun in each town and, in practice, was about 10 minutes slow in Bristol on London time and about 14 minutes slow in Exeter on Greenwich time. Travel was already uncertain enough that these differences mattered very little to ordinary people.
Did people have any idea of punctuality before the railways?
Yes, but time was organised differently. Events such as the chime of church bells, the opening of markets, and the mustering of troops had previously organised time, instead of one shared clock. Of course, being late meant missing an event, but it did not give rise to a guilty feeling of being late. The guilty, apologetic sense of being behind a shared minute arrived with the railway timetable.
