Well not so much, it doesn't look like Franklin was serious when he wrote about it in Paris. The impetus in the US was to align transport timetables and force States to be consistent, the Department of Transportation manages the Uniform Time Act.

It was WWI which convinced European countries independently to have DST to save energy in the Winter.

Along with the rest of Britain I suffered British Standard Time 68-71 which was 'permanently' GMT+1.

In Computing it's just UTC.

@simon_lucy @jef but WHO saves energy at WHAT TIME?

-> The energy is saved in the daytime during working hours. Thus it's in the interest of the people controlling those hours.

@rhold @jef

In two World Wars it saved coal.
Now it still makes sense at a time of high energy costs and the impact on emissions (probably relatively small).

Before we had a highly integrated world with transport times that ignore the local time related to the sun's progress everything was local. The time was governed by the most important church or public building in a relatively small area.

That can't be true now. What is worse is the slippage between continents when they change separately

@jef @simon_lucy @rhold probably doesn’t save energy these days, lighting has become efficient, aircon is still not.

@simon_lucy @jef @rhold true. But rapidly becoming more common. 45c in London? That’s going to motivate a lot of ppl to get AC.

It really isn't and a 45°C average temperature in Summer isn't going to happen this century, London might make a 30°C average. This year, though it was the hottest Summer, didn't get over about 23°C average with peaks of a few days over 30.

London is about 5° higher than the rest of the country, on a regular day it's about 2° but it was higher this summer.

We'll just complain about the humidity as we always have.
