Create a save and then fetch the date e.g. via Maniac Get Save Info function.
Assuming you are in Germany (UTC+1) and you save at 21:00 (local time) in EasyRPG Player then Get Save Info will report 20:00 in both Player and RPG_RT.exe.
When you save at 21:00 (local time) via Maniac Patch then both will report 21:00.
Reported here because the bug is in LSD_Reader::PrepareSave.
Found by korean_guy here https://community.easyrpg.org/t/the-time-of-the-save-information-in-maniacs-patch-is-different-between-the-output-on-the-pc-and-the-output-in-easy-rpg-player/1617/4
Thanks!
