Using the turnstiles for traveling to a specific time 🕰️
How do they use the turnstiles to choose a specific time/date or specified amount of time to go back in time?.
First time when the protagonists goes back a "few minutes" for the highway sequence, then "one week" for the airport and then "one hour" for the assault on Stalask-12.
The film did not mention or indicate how they chose a specified amount of time or a specific time/date. I didn't see or hear anything about a "chrono calendar" on those turnstiles.
