Time Keeps on Slipping

All of the Nuclear Mutants have names. There is Grotrian (named for a piano company) [misspelled in the DVD subtitles as "Grotreant"], Thorias (the Norse god Thor with a generic ending), Arachnion (because he's a spider), Armo (because he has five arms), and Lasero (because he shoots lasers).

The professor says that when time jumps forward, people continue acting normally but simply have no memory of what happened in-between. If this is the case, why would the group be standing in the stadium at the end of the baseball game, then jump forward in time but still be standing there the next night when the circus has set up? This isn't what they would normally have done if time had passed at regular speed.
