I think leap seconds and other time strangeness would prevent physical clocks from being totally reliable. AFAIK time is now implemented as being always monotonous, but you could get the same timestamp for multiple actions which are actually executed sequentially. Incrementing the local logical clock on every action is guaranteed to be safe.

That's why we have TAI[0]

Neat, TIL. You can still have multiple actions happen at the same time increment with multi threading.
