How time is handled in A Christmas Carol
1. Moving from present to past to future and back to present
2. Spirits are time travelers who enable Scrooge to be reminded of his past and warned about his possible future
3. Pace increased by threat of Tiny Tim's death and Scrooge's own death
4. Clock strikes to emphasise little time left for Scrooge to change
5. Time manipulated by Dickens so Scrooge can return to Christmas Day
