64 bits only cover about 7 months at picosecond resolution, so it's possible that 64 bit timestamps will be too small sometime this century, depending on how tightly synchronized the world becomes. An extensible timestamp might not be a bad idea and could still be kept under 64 bits for currently practical purposes.
- Sean1708 10y agoFor picosecond resolution to be useful wouldn't clock rates need to be on the order of THz? Otherwise what advantages would ps resolution give you over ns?
- mcbits 10y agoBulk data processing clock speeds could still be lower, but some devices may need THz timing, for example to align and integrate data from a swarm of sensors in motion relative to each other. Imagine trillions of 1-pixel cameras that know exactly when, where, and in which direction each pixel was captured (but not necessarily capturing literal image data).
