Stratum 1 NTP-сервер на Raspberry Pi в 2026 году: DCF77 + GPS/PPS, chrony, libgpiod v2

Stratum 1 NTP-сервер на Raspberry Pi в 2025 году: DCF77 + GPS/PPS, chrony, libgpiod v2, когда все туториалы по «точному времени на Raspberry Pi» сломаны на современных системах. Разбираю почему — и показываю как сделать правильно.

Stratum 1 NTP-сервер на Raspberry Pi в 2026 году: DCF77 + GPS/PPS, chrony, libgpiod v2

Es ist mal wieder Zeit für meinen halbjährlichen Rant zur Zeitumstellung.

Was? Nein, nicht wegen der Umstellung an sich. Sondern weil wir seit vielen Jahren eine zuverlässige, datenschutzkonforme Technologie für stets genaue Uhren haben, die von viel zu wenig Geräten genutzt wird: #DCF77

Penso che ogni marca/modello faccia a sé. Di solito gli orologi/sveglia da tavolo consumer sincronizzano col #DCF77 europeo appena accesi e poi una volta al giorno solitamente nella fascia 02:00-4:00 di notte, ma alcuni modelli sincronizzano anche più volte al giorno

BTW leggo che il segnale in radiofrequenza trasmette 59 bit ogni minuto, quindi volendo si potrebbe sincronizzare anche 1440 volte al giorno (ovvero 60x24)

@valhalla

Esatto, sono estremamente sensibili alla posizione, ma anche agli orari in cui si sincronizzano (segnale #DCF77 in #Europa), spesso lo fanno una sola volta al giorno e se lo fanno poco prima del cambio orario, uno per un giorno si tiene l'ora "sbagliata"; riesco a tollerarlo anche perché questi cambi orario avvengono sempre nei sabati notte

This “timestation emulator” has helped me twice to synchronize a radio controlled clock that is usually hard to synchronize against the #DCF77 #time code transmitter in #Frankfurt:

Highly recommend #hack! 💯

Time Station Emulator

Turns almost any phone or tablet into a low-frequency radio transmitter broadcasting a time signal that can synchronize most radio-controlled ("atomic") clocks and watches. Runs entirely in your browser with no installation or signup.

And yes, I too want my #car to be simple, stupid, intuitive and just function.

Cuz lets be honest noone but old #Boomers want to pay 4+ digits for a #NavigationSystem when even my first #Android #Smartphone over 15 years ago already delivered a better experience.

  • Just gimme a mic, amp and speakers that don't sound like ass and let me bring my own #music, cuz the only #Smartphones that I'm aware of that don't offer FM #Radio are #iPhone|s...

@newsthump shit like this is why I demand every device with a clock to support either #DCF77 or #NTF because I won't unfuck that clock!

@ChcpIsa @FraumitFahrrad: Gibt es mittlerweile #Lichtwecker mit #DCF77 (aka #Funkwecker) oder #NTP (und damit Internetanschluss 😱)?

Mein letzter Lichtwecker ging schon nach 'nem Monat um ein paar Minuten daneben, obwohl "Philips" draufstand. 🤬 → Tonne

This makes me happy. Radio controlled clocks perfectly in sync. #dcf77
