   In what sense?  *Proper time* is absolute/universal time, just there is no   
   absolute origin: so every (working) clock ticks it, just sync them and they   
   stay in sync.  Indeed, clocks drift because of space-time travel, not   
   because they slow down (most presentations are simply and completely   
   wrong in that sense)...
