This is an update of an Acme School of Stuff item... but it's still 15 years old, so the information is a little outdated, but interesting.

That's true. Only the older ac motor driven clocks relyed on the powerline frequency, but there are probably millions of them still out there on the walls.

quite interesting video. Remember the blackout of 2003?

That was so hardcore. Nowadays most of the facilities are upgraded and if i remembered correctly, a more advanced and state-of-the-art system was completed a year later back in 2004....couldn't remember that much, but despite that, i love this video.

Where I live the electricity supply won't keep your clock on time. It won't even keep your computer running long enough to

I see. Thanks for uploading these videos. I remember your other series on TVO... you taught me how a CRT works amongst other neat stuff.

Great stuff. I understand that electric clocks no longer rely on the mains frequency to keep good time.
