This might be the Berry Glitch

Q: What is the Berry Glitch?
A: The Berry Glitch is the nickname for a glitch in the coding of Pokemon Ruby/Sapphire that basically stops the game's day counter moving. This stops time-based events such as berries growing, the Lilycove Dept Store's sale, and trainer re-battles from happening (for a full list of events affected by the glitch see the section later in the post). It can be fixed relatively easily, but unfixed it can seriously hinder your enjoyment of the game. It usually only appears on a cartridge that is exactly one year old, but it has been known to appear on newer cartridges for some reason.

See here on how to fix it:
