How I got here
- Started with
- “clocks in distributed systems”
- Ended at

The Trail
- “clocks in distributed systems” (google.com)
- Lamport timestamp (en.wikipedia.org)
- Vector clock (en.wikipedia.org)
- Network Time Protocol (en.wikipedia.org)
- Spanner (database) (en.wikipedia.org)
Google solved it by putting GPS receivers and atomic clocks in the datacenters
