Requirements for wallclock (2757789531000)

• Provide the best possible time transfer over
  arbritrary networks between clients and servers.
  (Target average better than 1ms)
• Make use of any available HW support. (low power)
• Secure identification of time source UTC(k).
• Secure transfer client-server-client without
  (too much) server state.
• Identifying size of time errors between UTC(k)
  and server.
• Capable of handling leap seconds correctly.
• Require no external data (other source of
  information) to determine the correct time and
  date. (like 2e32 seconds)
• Standardized API and host representation of time
  and timescale(and make this independent of wire
  format). Maybe planet independent?
• Wire protocol and algorithms to be separated
• Future wire format to support 1 picosecond
  resolution
