Time anomaly or technical malfunction?
Today my radio alarm clock, which usually wakes me up quite reliably in front of the news, only came after the news. Yesterday he was a little late already.
My alarm clock is an older model, which has had a problem with tuning the transmitter for some time. That's why I thought at first that the alarm clock was finally broken.
But it turned out that the problem lay elsewhere. During the course of the day I learned that I was by far not the only one to see the alarm clock this morning showing the wrong time.
In the meantime I also found out why my alarm clock woke up too late today. The problem lies in the way the time is synchronized.
My radio clock (and many other clocks powered by mains power) synchronizes the time via the mains supply. For this purpose, the mains frequency is used as clock pulse generator for the clock. In Europe the mains frequency is 50 Hz and is normally stable enough to synchronize clocks.
But in the last few days this frequency has been slightly below 50 Hz on average. As a result, clocks synchronized via the mains frequency run slightly slower than normal.
One possible reason for the drop in the mains frequency could have been an increased power requirement at the frosty temperatures of the last few days.
If it goes on like this, I'll have to get an alarm clock with radio clock or correct the time manually every day.

Zeitanomalie oder technische Störung?
Heute ist mein Radiowecker, welcher mich normalerweise recht zuverlässig vor den Nachrichten weckt, erst nach den Nachrichten angegangen. Bereits gestern ging er schon etwas zu spät an.
Bei meinem Wecker handelt es sich um ein etwas älteres Modell, welches bereits seit einiger Zeit ein Problem mit der Sendereinstellung hat. Daher dachte ich auch zuerst, dass der Wecker nun endgültig kaputt sei.
Aber es hat sich gezeigt, dass das Problem ganz woanders lag. Im Laufe des Tages habe ich erfahren, dass ich bei weitem nicht der einzige war, bei dem der Wecker heute morgen die falsche Uhrzeit angezeigt hat.
Mittlerweile habe ich auch herausgefunden warum mein Wecker heute zu spät geweckt hat. Das Problem liegt in der Art wie die Uhrzeit synchronisiert wird.
Bei meinem Radiowecker (und vielen anderen mit Netzstrom betriebenen Uhren) wird die Zeit über das Stromnetz synchronisiert. Dazu wird die Netzfrequenz als Taktgeber für die Uhr verwendet. In Europa beträgt die Netzfrequenz 50 Hz und ist normalerweise stabil genug um damit Uhren synchronisieren zu können.
Aber in den letzten Tagen liegt diese Frequenz im Durchschnitt leicht unterhalb von 50 Hz. Dies führt dazu, dass über die Netzfrequenz synchronisierte Uhren etwas langsamer laufen als normal.
Eine mögliche Ursache für das absinken der Netzfrequenz könnte ein erhöhter Strombedarf bei den frostigen Temperaturen der letzten Tage gewesen sein.
Wenn das so weitergeht, muss ich mir wohl einen Radiowecker mit Funkuhr holen, oder die Zeit täglich manuell korrigieren.
Das habe ich noch nie gehört - spannend!
Ich glaub aber eher, dass wir in ein paralleles Universum gesprungen sind. Ich schau gleich mal, ob Nelson Mandela noch lebt! 😂

I know the feeling. :) After reading your post checked my clocks... and here is a result: my computer time is 12:57; on laptop i can see 13:03 ; my clock shows 13:12 ... and finally my phone "says" its 12:59. Lol. Tell me i'm lazy but before i gave up, tried few times to change them all on exact time and that didn't work. So... in fact i live in "meantime time" now. lucky me i can afford on it. lol

Yeah the problem is 50 Hz itself. All these electric digital clocks use the AC frequency as the clock sample frequency. In India, we do not get the constant 50 Hz. At some places the frequency is as low as 45 Hz while at some places is 50+ Hz. And this is not constant throughout the day.
Hence these digital clocks always loose or gain time.
A better (table) digital clock would be one with Quartz crystals.

Oh, if the frequency differs by 10 %, then my alarm clock would go 2.4 hours too slow per day.

That's a pretty major discrepancy. More reason to switch to battery operated quartz clock.

Do these radio controlled clocks work in India? They'd be even more reliable than quartz clocks. But I'm not sure about the international infrastructure for the senders.

Betreffen diese falschen Uhrzeiten im Mobilfunknetz eigentlich auch Smartphones, die ihre Uhrzeit über NTP mit dem Netzwerk synchronisieren?
Was das Problem mit dem leeren Akku betrifft, so lassen sich Smartphones ebenso wie Radiowecker natürlich auch am Stromnetz betreiben und haben zudem den Vorteil, Ausfälle über den Akku wegzupuffern. Wo man einen Radiowecker ans Netzanschließen kann, kann man dies auch mit einem Mobiltelefon machen. Umgekehrt geht ein Radiowecker komplett falsch, sobald ein mal der Strom ausfällt.

Yes, if you have network-capable devices, then NTP is a fine thing.

I don't have any others... except a watch that doesn't sync time at all, but the second watch I own is network-capable. All my other devices that require or show time are network-capable as well. That why I never thought about how the radio clocks synchronize their time 😅 - Thus, thank you very much for sharing.

But wait, 2-3 days ago I looked at my phone and my desktop time, and it was different.. Can this be somehow connected to this issue? It seems not, because both PC and mobile phone use internet... But strange...

The question is when and how often they resynchronize over the Internet. I doubt that they directly depend on the frequency in the power supply as both a PC's mainboard and the phone are not directly connected to the AC power supply system. Both of them have AC-DC converters, phones (and laptops) can even be entirely independent of the grid as they of course have batteries. So if your problem is related to the frequency in the grid, then I assume that's due some other device sending your devices time data. I'm not sure whether infrastructure in the mobile network relies on the frequency to provide time information.

It's been a while since I've had an issue with a clock that continuously gains or loses time.
However, for some reason, both in my car and with our alarm clock, they will gain or lose a few minutes then stay there.
So, there must be some kind of stop mechanism that prevents it from getting too far out of sync, but never ever brings it back, until I get annoyed enough to do it myself. Really odd.
Doesn't happen to any other clocks. Just those two.

Interesting post! Many clocks (analog and digital) use a quarts crystal and a battery. However it is cheap to use the AC utility frequency, especially in things like coffee pots and ovens that have temperature changes that would create error for the quartz.
I have read the power company will schedule frequency offsets to compensate for corrections of error. In other words if the frequency is low enough to loose time, then the utility provider will schedule increases to synchronize time.
Your post got me wondering if the power company was motivated to correct for time, as mentioned above. This site has some interesting info, as did wikipedia

WOW!
This post just officially blew my mind.
Does this mean we risk a mass epidemic of people clocking in late for work and missing appointments?
I have often wondered if the earth suffers an EMP, how will this affect many of the worlds major timepieces. I realise that the chances of this happening in all continents simultaneously is not likely although it IS possible.
The question this raises for me is, in this eventuality is it possible that we lose a few seconds of time and could this create a scenario where time is never correct again?
We would have ZERO chance of ever knowing the correct, original synchronized time ever again...No matter how many aeons man reigns over the earth!!!
I have no idea why this concept makes me feel a little sad, but in this bizarro alternate reality I am creating in my strange...STRANGE mind I feel that if this were to happen, we would have lost something that could never be replaced.
OR...Perhaps I just think too much and your fascinating time related explanation ignited something in my mind, maybe I have the nucleus of a short sci-fi story formulating.
Thankyou for taking the time to explain the twisted reality of the logic that caused this strange Chrono-Flux anomaly I would genuinely NEVER have guessed the explanation and so am indebted to you forevermore ...Although however long that is MAY cause some debate :)
