@AaronDavid #DST should be outlawed and #Unixtime mandated globally.
I'd like to use the opportunity to reiterate my point about abolishing #DST, in a slightly different form.
Ask yourselves a bunch of questions:
1. How many devices automatically adjust to DST today, using a date-based algorithm?
2. How many of them get automatic timezone data (or software) updates? Or at least get updated periodically? And how many are going to require an intervention to get the algorithm updated?
3. How many of them actually permit algorithm updates? How many of them get software updates? And how many use software that was long abandoned, and perhaps the sources were lost in the mists of time? In other words, how many "can't do", and we're stuck with doing manual adjustments every half a year to keep the local time correct?
4. How many of these synchronize their UTC time, therefore overwriting our local adjustments? How many of them will permit disabling this synchronization, and how many will require us to physically block it instead? And how many will end up quickly collecting clock drift once the synchronization is off?
5. In the end, how many critical devices we're going to miss entirely, just because they "always worked" and nobody remembers about them anymore?
Sometimes I feel like people are thinking of abolishing DST as if they were living a hundred years ago. Unfortunately, today we're deeply computerized, and such a change requires a lot of preparation work, and readiness to intervene when things fall apart. What it doesn't require is a bunch of noisy politicians, waking up a month before each DST switch to philosophize on their couches. And in the end, such a reform will definitely mean trashing some otherwise good hardware that doesn't get updates anymore.
El cambio de horario es un atentado contra la salud. Rechazarlo es la mejor medicina https://meanmicio.org/2025/03/30/el-cambio-de-horario-es-un-atentado-contra-la-salud-rechazarlo-es-la-mejor-medicina/
#DST, #HorarioDeVerano, #Salud
Yo también era "team horario de verano" hasta hace no mucho. Pero me he dado cuenta de varias cosas:
• «Nuestra relación con la luz del sol depende del uso horario y no del huso horario». Esto se lo leí a un divulgador hace un tiempo. En resumen: No importa lo que marque el reloj, lo que importa es lo que hacemos en esa hora; solo hay que ver cómo, con el mismo horario que Francia, Alemania o Países Bajos, no usamos nuestro tiempo de la misma manera que estos países.
• Empiezo a valorar mucho más tener más luz solar por las mañanas que por las tardes. "¿Qué más te da tener luz para trabajar, mejor tenerla para el ocio, cuando salgas del trabajo?" es un buen argumento a favor del horario de verano. Sin embargo, yo necesito luz solar para despertarme mejor, no dejamos de ser animales diurnos, por mucho que intentemos negarlo. Salir de casa de noche para ir a trabajar es muy triste.
• Si finalmente se siguiera haciendo el cambio de hora, votaría por volver a lo que se hacía antes de 1996. He leído que en España, hasta ese año, el horario de invierno entraba en vigor a partir del último fin de semana de septiembre, no de octubre, como se hace ahora. Ese cambio actualmente llega tarde porque, siendo en España de 7:00 a 8:30 las horas habituales de entrar al trabajo, la ventaja que sacamos dura tres semanas, tras las cuales volvemos a entrar al trabajo de noche. Un sinsentido.
• Conclusión: Que se terminen los cambios de hora, nos quedamos con el de "invierno" para todo el año y cambiamos nuestros "usos" horarios si hace falta para ajustarnos al cambio. Ejemplo: Entrar antes al trabajo, comer antes, cenar antes...
Gracias por asistir a mi charla TED (vaya rollo acabo de soltar).
Hoy es el día en que todo el mundo refunfuña pidiendo que España vuelva a El Huso Horario Que Le Corresponde creyendo que así tendrá más luz en las tardes de invierno.

Let's take a moment to remember the guy who made sure we don't have to change Every Goddamn Clock today, David L. Mills, creator of Network Time Protocol (NTP) who passed last year.
My wristwatch is synced to my phone, which is synced to the internet, which knows that time it is right now thanks to David Mills. Cheers to his memory 
And so it begins, the ludicrous and outmoded annual move to BST. Its proven to cause stress on the human body, mental trauma and every year contributes to a 48 hour increase in deaths from heart failure. But we do it anyway.
I've been waking early of late. Part of the cause is likely the mornings getting lighter.
Now, whilst the UK's shift to DST (30th March) will partially reverse that, this will not be a good thing, because it just means I'll go through the same thing *again* when morning light levels have shifted by another hour.
And I know I'll struggle for a few days to a week with the "one hour less sleep" due to the change.
Abolish DST ! The switching is more of a problem than any benefit from, in effect, shifting business hours!

Guy about to invent #DST: "Hold on-"
The real reason Dr. Manhattan went to Mars is that even with his non-linear perception of time he still couldn't figure out how to schedule online meetings when only some people switch to #DST
(Mars does have seasons btw)
@sundogplanets I think #DST should be outlawed as it's #torture and a #scam!
I am a daylight saving time zombie. Will probably play this song on repeat today.
When will these people stop this nonsense!? #DST

Thanks for making a good case! @gleick
