Submerged for Weeks or Months
Submarines are designed to operate submerged or at the ocean’s bottom, so seeing daylight and nightfall is uncommon. As a result, once you’re inside an operational submarine, it’s very simple to lose track of the time, especially when you consider how long these vessels may stay submerged.
Even though you’re on a submarine, don’t worry – there is a clock available to everyone! The point is, it might be pretty challenging to determine what time it is without looking at the clock.
