After months of anticipation, the long-awaited first trailer for Avengers: Endgame finally arrived on Friday, providing a look at the new status quo of the Marvel Cinematic Universe following Thanos' devastating finger-snap, and laying to rest some rumors while raising others. First and foremost is how just how much time has elapsed between the events of Infinity War and its upcoming sequel.

There had been rumor of a five-year gap between films, but the Endgame teaser suggests that isn't the case. That said, there are moments in the new footage that seem to indicate a time jump of some kind -- perhaps not years, but nevertheless significant.

From beginning to end, there are clues that speak to when Avengers 4 takes place: Iron Man's recorded message, Clint Barton's appearance and Ant-Man's plea, to name a few. But each appears to suggest something different.

Tony Stark, Adrift in Space

Let's start with Tony Stark. At the beginning of the trailer, he's adrift in space board the ship in which the Guardians of the Galaxy traveled to Titan in Infinity War. The first clues come in the message he's recording for Pepper Potts, in which he reveals his food and water ran out four days earlier.

There's no way of knowing how well-supplied the Ravager vessel might have been, or whether Tony left Titan immediately after the events of Infinity War; he could have remained on the devastated planet to scavenge materials and supplies, and to make repairs. If we remain conservative and assume he left immediately, and that he was limited to the supplies already on the ship, it's not beyond the realm of possibility that Tony would be able to survive for at least a couple of weeks. Keep in mind that the ship was used by the Guardians, so presumably there would have been enough food, water and oxygen to sustain six people.

But who knows when in Endgame this scene takes place. It could be in the beginning, but there's also a good chance it takes place much later, when Captain Marvel is brought into the fray. Many have guessed that Carol Danvers will rescue Tony before she meets the rest of the Avengers and helps to defeat Thanos. For now, however, this sequence suggests, say, three to four weeks have elapsed since the end of Infinity War.

How Long Has Hawkeye Been Ronin?

The next potential clue is the appearance of Hawkeye, or rather his new alter ego, Ronin, which fans had been anticipating for months.

Coupled with the new identity, the rage and grief written across his face suggests he's experienced tragedy. Given that Thanos wiped out half of all life in the universe, it's likely that Clint Barton's wife and children among the victims, leading the former archer on a rampage as the mysterious Ronin.

Presumably, Clint wouldn't have taken such drastic actions immediately after Thanos' finger-snap. He would likely take some time before venturing out with a new costume and weapons. However, Natasha Romanoff is there with him in Japan, and because she recapped events earlier in the trailer, it's likely this scene takes place near the middle of the film, after even more time has passed.

Hey, You Remember Ant-Man, Right?

The most curious sequence in the trailer is the very last, when Scott Lang approaches the security camera at the front gate of the New Avengers Facility. As he's trying to persuade Captain America and Black Widow to let him in, he says, "We met a few years ago ... at the airport," which is an interesting choice of words. It leads us to ask, how many is a few years?

According to directors Joe and Anthony Russo, Avengers: Infinity War takes place two years after the events of Captain America: Civil War. And the mid-credits scene of Ant-Man and The Wasp takes place at the same time as the climax of Infinity War, leaving Scott temporarily stranded in the Quantum Realm.

It's difficult to imagine Scott could escape the Quantum Realm virtually immediately; it could take anywhere from days to a year, even if, from his perspective within that alternate dimension, it seemed like immediately. Remember, time passes differently in the Quantum Realm. Adding to the curiousness of the scene is Cap's reaction to the security feed. He asks, "Is this an old message?" Because Scott disappeared into the Quantum Realm, Steve and Natasha would have presumed he was among Thanos' victims. Seeing him at the front gate would be a shock, no doubt. But, would they really have reason to think it's an old message if a substantial amount of time -- perhaps years -- had passed?

The MCU films tend to take place in something approaching real time: The events of Infinity War are set two years after those of Civil War, just as the films were released two years apart. There are a few exception, such as the upcoming Captain Marvel, which is set in the 1990s, but Avengers: Endgame probably won't be one of them. It's safer to assume the film takes place between six months to a year after the events of Infinity War. Everything we see in the trailer, from Iron Man's speech to Ant-Man's reappearance, fits into that time frame, even if you do have to rely on suspension of disbelief, just a little bit.

But we're primarily focusing on beginning of this film. If you've been keeping up with rumors and leaked set photos, you'll see there's a pretty good chance the Avengers will employ time travel to undo Thanos' culling. So who knows when the rest of the film will be set? We'll have to wait for the film, or at least the next official trailer.

Avengers: Endgame will release on April 26, 2019.
