But why do we have different time zone definitions at all?
Why is the clock hand position so massively important to us?
Consider, there is a natural time definition:
Night is when it is dark outside and day within light period.
Day is between sunrise and sundown and night vise versa.
When discussing why people want to use UTC+1 or UTC+2 the whole year I either hear that they don't want to get up within darkness in the morning or they don't want to go to bed within darkness.
That means daylight is important to us.
When you look deeper into it you will recognise that lots of people follow the sun. East, West, North and South - sunrise and sundown is different and even using same time zone there are huge regional differences. Eastern people often start work at 8:00 while Western start at 9:00. Also regionally different is the school beginning - it depends between 7:30 and 8:30. There are regions where the usual lunch break time already starts at 11:30 while we have other regions inner the EU where usual lunch break start is 13:00. Usual dinner time also differs regionally between 17:30 and 20:00.
Looking to the US you will find bunch of people already awake at 5 AM and going to bed at 9 PM.
What I also recognised: People with flex time jobs often start work earlier in summer as in winter - kind of depending on sunrise.
That just shows that clock time not really matters to our habits.
So why it the EU discussing to use a fix time zone inner EU? For what do we need clock time?
We need it for appointments - for scheduling.
But does it really matter if we are doing it using UTC+1, UTC+2 or UTC+23?
There already is a global time that is used for world wide business. A global time that our computers use. It is called UTC.
Why not just using UTC and live by following the sun?
Does it really matter to do lunch at 11:30 or 13:00? Or is it more important to us that lunch is close to midday - when sun is most high? Even when clock hand would say it is whatever odd time.
It is up to you and your community - when schools will start their services. It is a negotiation between you and your boss when you will start working.
My recommendation for the European Union is that they should remove any time zone guideline. Let's just using UTC for appointments all over EU and let the freedom to people and communities to decide by their own how organise their day-night-rhythm.
