It is very true.
A similar event happened in Europe a year ago (also due to problems in former Yugoslavia) and all electric clocks in my house (microwave, oven, alarm clocks) went out of sync temporarily. I was just as surprised as you.
Basically, it's exactly the devices that lose track of time in case of a power outage, and that you need to manually adjust for daylight savings time, that are synchronized to the grid. Devices that use a battery (such as laptops, mobile phones, and CMOS clocks in PCs) must necessarily use some other means.
It doesn't seem to be much correlated with price either: my alarm clock cost over $100 and it was still affected. Surely at that price point they could have afforded a crystal oscillator in the design, if they wanted to, but it seems this just isn't typically done.

- laurent92 6y agoAs an industry, it requires a special customs declaration + fire safety measures on boats and planes when you transport an oven with a battery inside. That may be the reason for not using battery-backed ovens, and relying on the power supply.

One reason that it might be expensive is that it needs a lot of high luminance hue shifting LEDs, and possibly I overpaid a bit (there do seem to be much cheaper competitors) but it was still a good investment because it does make my mornings a lot more pleasant.
