The first you should do after you hatched the egg is to go to the IV man in Nimbasa City and let him check the breed (HP, Def, SAtk, SDef and Spe have to be the top values). That is the best way to check if Timer0 has screwed over you. That is a line we don't quite get. The only way that might happen is when you are in another seed, see first paragraph. When not, then you should look it up again. Do not forget to display all of the possible PID frames and to confirm your frame by listening to Chatot; you probably already know - because of moving NPCs.
