Metal Gear Solid V: The Phantom Pain - Every Screenshot You Need To See

As you'll be out in the open world for sometimes hours at a time, part of how you'll infiltrate any number of enemy bases will be dependant on the time of day, as it'll constantly be changing in semi-real time. Busting out the Phantom Cigar gives you a cool time-dilation visual whilst also forcing the world around you to advance, putting any number of things in motion like guard pattern-changes and the appearance of supply drops.
