===Effects of changing the clock===
If the game detects a different clock, either by changing the date or time of the system or by booting the game in a different system and saving, time-based events will be affected differently.
The following time-based events can be done by directly changing the clock to the time window in which they are active:
* The Bug-Catching Contest.
* The event at Mt. Moon Square.
* Taking commemorative .
* The availability of items at the Pokéathlon Dome's Athlete Shop.
* The special encounter in Union Cave.
* Pokégear radio shows.
* Obtaining the .
* with the Gym Leaders.
* The rematch against at Indigo Plateau.
* The S.S. Aqua voyage.
* The opening of shops in the Goldenrod Tunnel.
* The appearance of the Week Siblings.
The following daily events can be done by changing the clock to 23:59 and letting the clock roll over to the next day in-game:
* at the Goldenrod Radio Tower. The password will not be available right after the clock rolls over. Saving the game after midnight, then changing the clock for a second time to when (or waiting until) her show is on air (2:00, 5:00, 8:00, 11:00, 14:00, 17:00, 20:00, or 23:00) is necessary.
* 's massage in Pallet Town. The massage will not be available right after the clock rolls over. Saving the game after midnight, then changing the clock for a second time to when (or waiting until) the massage can be requested (15:00–16:00) is necessary.
* Mass outbreaks.
* Obtaining a new trendy phrase from the old man on .
* Picking Apricorns from trees.
* Entering the Pokémon Lottery Corner at the Goldenrod Radio Tower.
* Receiving Apricorn Balls from Kurt.
* Receiving Seals from the little girl in Olivine City.
* The Trainer House battle in Viridian City.
The following time-based events are impacted negatively if the game detects any time change:
* Berry growth: instead of calculating how long it has been since the game was last saved and matching the Berry's timer to the system's clock, the Berry's timer resumes right from when the game was last saved.
* Area upgrades at the : the invisible day counter will freeze for 24 hours, period after which it will resume counting days from where it left off when the game was last saved. Just like with Pal Park in , if the clock was changed, the game to needs sync with the new time so that the penalization period starts running. This can be accomplished by booting the game and saving. Otherwise, the penalization period cannot begin nor end. If the game was booted in a different system, the penalization period can be prevented simply by not saving and, if available, returning the game to the system it's synchronized with.
