The 64 bit clock will overflow about 292 billion years from now. That's long enough for me. --- Worrying about 64-bit time overflow is like worrying about IPv6 address exhaustion.

Running out of IPv6 addresses is more likely than you think: https://ripe77.ripe.net/archives/video/2287/ https://ripe77.ripe.net/archives/video/2287/

I'm going to set my cryogenic wake-up for then and make a whole bunch of money.

  Be careful, it the cryogenic controller might overflow and wake you up right after the big bang!

  > ~2^93 is enough to individually address every subatomic particle on Earth. IPv6 address exhaustion is very unlikely, but it's more likely than some may have thought about. Only 64-bit of the 128-bit address space was fully utilized, it means the utilization rate is less than 0.0000000000000000055%. And no, it's not a bug, it's a feature. The huge address space was intended to make address assignment, configuration, and routing easier. That is, in the real world, the first 64-bit part becomes the network identifier, and the last 64-bit becomes the device identifier. Ideally, everyone's home, business, institution, datacenter, etc, will get a unique, globally routable 64-bit network prefix. So no, every subatomic particle on Earth will not get its own IPv6 address. But, everyone of the 7 billion people on Earth can have prefixes for their 263,524,915 personal computer networks.

  Where did you get 2^93? I seem to get 3.6 × 10^51 which is about 2^171. Meanwhile the 128-bit addresses are only enough to give one to each cubic-micron nanobot on Earth (https://www.xkcd.com/865/ https://www.xkcd.com/865/).
