Time change

Time change (also referred to as a day/night cycle) is a feature from Super Smash Bros. Brawl onward where some stages and areas depict various transitions in time over the course of a match. All effects are purely aesthetic and have no impact on gameplay.

The extent of transformation depends on the stage. Some stages show rapid changes in time, while others change in response to the console's internal clock when the match is started. Three time changes also take place in real-time, with replays of these saved matches featuring the time based on when the replay is played back.

All-Star Rest Area (SSB4-3DS)
Super Smash Bros. 4's All-Star Rest Area is unusual amongst time-changing stages in that it does not change while the player is in it. Instead, the stage progresses from dawn to dusk as the All-Star Mode is progressed through.
 * Dawn: Violet sky with clouds that are tinted pink. Appears after the first stage.
 * Midday: Clear skys with few clouds. Appears after stages 2 and 3.
 * Evening: A yellow sunset with clouds that are tinted orange. Appears after stage 4.
 * Night: A dark sky with numerous stars and some galaxies. Appears after stages 5 and 6.

Battlefield (SSBB)
Battlefield features a day to night cycle. A sundial behind the playable area shows the time of day as well. The cycle lasts three minutes.


 * Evening: Everything turns more dark-red (more in the background, less on the stage).
 * Night: Everything turns more dark-blue (again, more in the background than on the stage), the sub-platforms turn dark-blue with small blue stripes and stars and the moon can be seen.
 * Dawn: Light is seen on the mountains range in the background.

Battlefield (SSB4)
This stage has a daily cycle, like Brawl Battlefield, on both the Wii U and 3DS versions of the game. The cycle lasts two minutes.

Battlefield (SSBU)
While Ultimate's iteration of Battlefield does not feature a day-night cycle, it instead features a periodically occurring solar eclipse to similar effect, causing the background to darken briefly before lightening up again.

Gaur Plain
Gaur Plain undergoes a day-to-night transition. The stage starts off in its day configuration. In and Ultimate, Metal Face appears at night.

Home-Run Contest
In both Brawl and Smash 4, if the Sandbag is hit far enough, the time will change from day to evening, and then night. If hit even farther, it will change from night to day again.

Minecraft World
Minecraft World features a time change which, like in Minecraft itself, is not identical to real-time. The time of day affects which mobs will be seen in the background; during the day, peaceful ones such as farm animals and Villagers will wander about. In the evening, Villagers return to their homes. Monsters come out at night, but burn up in the morning, and the Villagers come out to repeat the cycle.

Prism Tower
Prism Tower's time change aspects are linked to the where the fight is taking place. At the ground level of, the stage takes place in the day; as the stage begins to go higher up Prism Tower time passes, and at the apex the stage turns to night, returning to dawn during the descent to its initial form.
 * Dawn: Occurs at the start of the match, as well as when the stage returns to the base of Prism Tower.
 * Evening: Occurs halfway up the tower; the light is tinged with yellow and orange, as to simulate sunset.
 * Night: Occurs at the top of the tower, as well as when the stage flies in the skies of Lumiose City. The lighting becomes dark blue as to simulate night, and numerous buildings seen below the stage have their windows lit up. The Prism Tower itself also features uniquely colored lighting on its spire. In, the stage's Ω form is permanently set at night, while Ultimate features the entire cycle.

Smashville
Like the Animal Crossing games, Smashville's time changes are based on the system's internal clock; the variation is based on the current time when the stage is loaded, and unlike the Animal Crossing games, it does not change in real time. The system clock also determines what time shows up on the clock of the Town Hall building. True to the source, K.K. Slider appears and holds a concert on Saturdays between 8:00 PM and 12:00 AM.


 * Dawn: Occurs between 4 AM and 7 AM. The sky is pale blue.
 * Day: Occurs between 7 AM and 4 PM. The sky is deep blue. In Brawl only, the stage has a yellow tinge.
 * Evening: Occurs between 4 PM and 7 PM. The sky is orange, and lights on the stage and background houses are turned on.
 * Night: Occurs between 7 PM and 4 AM. The sky is dark, making the lights more visible. Also, constellations can be seen in the sky.
 * Saturday, 8:00 PM - 12:00 AM: K.K. Slider holds a concert in the background, playing one of six different songs.

Town and City
Like Smashville, the time of day changes on this stage depending on the system clock, using the same mechanics. The clock on the Happy Room Academy building during the city phase of the background transition also matches the system clock. K.K. Slider still performs concerts on Saturday nights.

Umbra Clock Tower
In Super Smash Bros. 4 and Super Smash Bros. Ultimate, the face of the falling clock tower face matches the system's internal clock. It is even possible to see the clock hands moving. If the game is paused, the clock stops moving; when the game is un-paused, the clock skips ahead and resumes moving from the time at which the game was un-paused.

This stage uniquely features a seasonal cycle, with each season lasting about 30 seconds. The song  syncs to the different seasons, with one variant playing in Autumn and Winter, and another playing during Spring and Summer.


 * Autumn: The gigantic flowers go down and the background turns more orange.
 * Winter: The sky turns blue while the rest of the background is covered by snow, save for a few tips of grasses. It also snows.
 * Spring: The sun comes out, the snow disappears, and the grass appears while they are turning from brown to green.
 * Summer: The big flowers appear and everything becomes greener.

Trivia

 * Despite both PictoChat and PictoChat 2 technically having a clock visible at certain points, neither are affected by the system's internal clock and instead move at a predetermined rate. This is due to the hands of the clocks acting as platforms, facilitating the need to move in a regular pattern.
