Here is what the patch does:
-Applies gbata's RTC patch
-Adds a clock to every Pokémon Center
-You can reset the clock at any Pokémon Center
-You can view the time at any Pokémon Center
-The font has been changed to the one used in Pokemon Emerald
-The size of textboxes has been altered to the size they are in Pokemon Emerald, to accommodate the new Emerald font (however, Ruby/Sapphire colors are still used)
- The location of some clocks were moved for the sake of consistency across all versions and for aesthetic purposes.
- A script event was added to the clock in the Pokemon Center of the Battle Frontier.
- Clocks are now color-coded for each version; green for Emerald, red for Ruby, and blue for Sapphire.

These patches were tested on the VBA-M emulator and GBA hardware with an EZ-Flash IV.

All editing was done in Advance Map and consisted of creating a new palette and editing/moving/creating tiles.
