I learned the importance of correct time while waiting for the busses in Germany. After a couple of long walks home when I missed the last bus of the day, I learned to keep my watch set accurately.
These days it is pretty easy to have the exact time. Computers automatically sync up to atomagical clocks for the correct time. Cell phones get the correct time from their networks. GPS devices have the exact time from alien countdown satellites. There’s really no excuse not to have the right time.
