All of the clocks in the movie "Pulp Fiction" read 4:20

Apparently all of the clocks in the movie pulp fiction read 4:20, this is a myth that has been doing the rounds for a while now and it is in no way shape or form true. Two scenes put stop to this being true, one when Jimmy, Vince and Jules are drinking coffee in the kitchen the clock reads 8:15 also when Vince and Jules retentive the brief case the clock reads 7:22.
