Does anyone know a reliable way to skip days for leveling up the Johto Safari Zone? The closest method I’ve found is saving, changing the time to 23:59, waiting for the day to roll over, and then waiting until 12:01 to save and repeat for however many days need to pass. That method seems to work for some based on comments I’ve seen across the web and this youtube video (https://m.youtube.com/watch?v=SncihZQQZTs&t=4s), but I can’t get it to work for me and I also see a lot of comments saying it does’t work for them or saying it’s impossible to do.

Hardware is English SoulSilver and a DSiXL if that makes w difference.
