Pokemon Cannot Be Migrated For 24 Hours Internal Clock Pal Park Questions?

Pal Park Questions? - pokemon cannot be migrated for 24 hours internal clock

Pokemon is why I have a problem with the migration
I have my national dex, I have everything you need to had done the migration and successful.
But now I am asked to set the hours.
So, I went to meet so
and then, after I said that can not migrate for another 24 hours
then returns to the menu screen. I really have to wait 24 hours?
