Top, TIME and CPU columns

I have noticed this weirdness in top. Sometimes I can see no process having 
more than single percents in the (W)CPU column, yet there is one for that the 
TIME column is steadily increasing by 1 second per second. How is this (W)CPU 
  column computed? Shouldn't it report something like 1/NCPU * 100 or something?
