  It means how a particular chamber in the cylinder lines up with the barrel, in relation to the hammer fall. If the timing is off, the chamber might not be fully aligned with the barrel, when the hammer falls. And, the hammer can fall on most revolvers without the cylinder stop being engaged.
  
  Timing is adjusted by adjusting the hand's(pawl) relationship with the ratchet. This should be done by a competant gunsmith, who is versed in the procedure for your particular revolver. They need to check every chamber in the cylinder.

  On S&W revolvers, if you've just got to tinker with the timing never touch the pawl (bumps protruding from the back of the extractor).
  
  Do the hand (part that rotates the cylinder), as a new hand can be purchased if you do an 'OOPS'.
  
  The extractor is factory replacement only. They won't ship one out to you.

  A narrow interpretation would be lock up when the trigger is pulled while an expansive one would be the turning of the cylinder from start to moment of firing. I think timing begins when the trigger is engaged and ends when the firing pin hits the primer.
  
  How you change it depends on the revolver and the problem being corrected. If the hand turns the cylinder before the cylinder bolt clears the cylinder bolt cuts, there's a fix different than if the hand is not turning the cylinder into lock up at the moment of firing.
  
  So, what kind of Colt do you have .....? [;)]

  If you're going to try it yourself, practice on some cheap guns first.

  A revolver hand is technically a pawl and that feature on the cylinder the pawl engages is a ratchet.
  Changing cylinder end play will also affect timing.
  Double action timing involves different parts than single action timing.
  Not all revolvers use the same mechanical arrangement to advance the cylinder, position it and drop the hammer, so a timing fix for one isn't a cure for all.
  You have to explain your problem and tell us what brand revolver you're interested in.

  I am not attempting to fix a revolver just wanted a little education on the terms and procedure.
