If every device that has a timekeeping clock (such as, for instance, a microwave oven, which doesn't really need a clock anyway) that has to be set manually were to also have a small coil of wire and a tiny lump of silicon, the time could be set via Near Field Communication (NFC).
So, your digital
watches and VCRs or whatever it is people have these days could all be synchronized to the current time just by tapping them with your phone (assuming you have a phone with NFC, which I don't).
But I like the idea that a clock could be set by tapping one lump of technology against another. It would save many seconds of pressing buttons! One could even make money by selling a retrofit clock mechanism that supports this protocol.

||Put an MSF chip (small enough to fit in wristwatches) in the device. No user action needed.
||If each device were to have a tiny camera and an entire
whole computer with intelligence all on one board,
retrofitted (or modernfitted if you wish), you could simply
show the thing what the time is perhaps by holding up a
watch to it, or writing the time on a piece of paper and
holding that up to it. Itd have to be careful not to
recognise passing peoples faces or other body parts and
interpret them as a time.
||Would it be able to recognize the time presented, for instance, via the medium of interpretive dance, perhaps accompanied on a recorder ?
||What, like Kate Bush performing the time zones?
||Yes, but musical, and involving artistic talent.
||then you could send binaries.
