Ben in Tozeur, Tunisia + hotel clerk

Here's Ben in Tozeur, Tunisia. We he arrives at the hotel, he checks in under the name Dean Moriarty with the passport Sayid finds in "The Economist." He tells the clerk, Narjiss, that he's a "preferred guest" and then asks what day it is. It's October 24, 2005. Does Ben's means of travel also include time travel?
