It's odd that my BMW doesn't use it to set the clock. It's a pita changing the clock every spring and autumn!

Same with my 2018 VW. At least it has a DST toggle in the menu, so the most annoying part of changing the DST is left out of this process.

Any car with a built in gps or cell phone is picking up time signals from those transmissions, and at least using them internally in some capacity. Which doesn't necessarily mean one of them is used for setting the actual clock display.

A reason could be that the clock would show the wrong time if you took your car to Greece, Portugal, the UK or the Ukraine. That’s solvable by “jump one hour forward” and “jump one hour backwards” buttons, though. If they want to sell the same car worldwide, it would be a bigger problem.

  >the clock would show the wrong time if you took your car to Greece, Portugal, the UK or the Ukraine But why do you think that it'd show the wrong time? In my mind, if left as is, it'd show the wrong time, no? What's the first thing you check after you get up from your chair after your flight has landed at its destination? I know i'm looking a) at my smartphone b) for the (local) time and if it has c) changed automatically yet. Imagine you're making an appointment with a local restaurant and have to do calculations for the right time first, because your smartphone shows the time for your hometown?

    That signal broadcasts German local time. So, this would show the wrong everywhere local time doesn’t match that.

      True, looking again at the map on Wikipedia, it shows the signal is broadcast far farther than just Germany, something i forgot to take into account...

Even more odd if you know that also plain RDS has the time in it. Imagine my surprise, sitting in my old, beat up Opel Corsa after installing a high-end Kenwood radio which, shortly after turning it on, automagically set the time right. At first i was like "what the... is going on" and after digging in a little bit, i never understood why other manufacturers and OEMs won't do the same - they rather have you manually change the clock twice a year. Why?
