 CONT: When Mac & Gin are in the back of their car, driving to the  millennium party at the world bank, they synchronise their watches  at 23h00. She then mentions that every minute from then until  midnight, the atomic clock will gain a tenth of a second (thus  giving them the extra 10 seconds they need to transfer the 8  billion). Unfortunately though, 1/10 of a second, every minute, for  1 hour (or 60 minutes), gives them an extra 6 seconds, not 10  seconds.
