It's pretty astounding to me the number of pro-DST advocates in this forum. If you had hundreds of daily jobs on your platform and you happen to have some regular requirement to change them in unison, if a junior engineer said "let's just change the system clock to adjust for when we want the jobs to run", you would say no, because while it might be easy compared to changing the config for each of the jobs, the risk…

Imagine having a solution that already works with changing system clock but then some very big very important very senior very developer shows up and launches a multi-year project to redesign this, potentially opening pandora box of endless bugs. PhD in Job Security, typical shit I see in corporate.

To be clear if I showed up to a company running their own company NTP server that they desync twice a year to make timings work - I would absolutely try to migrate them away from that. Now if they are doing that there is probably bigger fish to fry... but it would be on the list.

That is why you run your jobs on GMT/UTC and not display time.

Well, it's not that obvious.

Some jobs should run every day at 8 am (e.g. torn on the temporary speed limit on front of the school), vs tasks that should actually run every 24h (e.g. feed the bacteria in exact time intervals)

Of all the things that cause obesity and sleep loss, is an hour change twice a year really a major issue?

There are measurably more heart attacks and traffic accidents after the switch.

Which switch? 1918?

I live in the Netherlands.

In the summer the suns up at 5 am. But at 5am I am asleep. I could get up earlier but that's pointless since school and work doesn't start until 8.30.

So in stead of having an hour of sunlight before school and work we all change our clocks to have an hour of extra sunlight in the evening in stead, which fits our cultural preference for social activities.

We could also, as you say, change every single sign, post and display of opening hours for every school, business and organisation at the same time to achieve the same effect.

But in the real world changing the clock is simpler.

Earlier quoted context omitted.

Elaborate. The intent of DST is to normalize variations in the time of sunrise between summer and winter. Places closer to the equator have minimal variation in the time of sunrise between seasons. They don't need DST. Higher latitudes have large variation (i.e. Seattle, where the time of sunrise shifts between 4am in summer to 8am in winter), so they benefit from DST or summer/winter hours. DST is one of the simples…

What people usually mean by abolishing DST is permanent summer hours. If your problem was sunrise timing, then problem solved - DST actually moves that earlier than you require twice a year for normal working hours (i.e. less sun in the evenings). Source: my own high latitude life.

Abolishing DST for permanent summer hours don't address the winter sunrise issue.

Under permanent DST, the sun rises around 9 AM in December in Seattle. That's far too late. I, and millions of other people, do not want to wake up 2 hours before sunrise and drive to work in the dark.

Under the current system (DST reverts back during winter), sunrise is shifted an hour earlier to around 8AM, which is manageable. I don't have to drive to work in the dark.

The government doesn't set the opening hours of businesses though either.

They do with DST.

That doesn't set the opening hours.

The bar near me has different opening hours to the library, and that has nothing to do with DST.

I guess you're fine commuting home in the dark? But regardless, you can navigate without light an hour before sunrise.

Do the anti-DST people understand what they're advocating for? Have a look at the sunset/sunrise graph for northern parts of the US https://www.timeanddate.com/sun/usa/seattle In Seattle, without DST, sunrise happens at 4:11am. Because of DST, it's pushed back an hour later to a more reasonable 5:11am. I am not awake at 4am, I have no use for sunlight at 4am, and I don't want the sun appearing that early. That hour o…

Hol up, don't fix time, there's a few guys in Seattle without curtains. Sorry everyone.

Curtains would make the sun set later in summer and rise earlier in winter?

So change it... just permanently. GMT+2 will always be there for you.
