@Theuberclips That is possible, though odd since the day roll-over (like for Daily Orders and such) for the NA server should be at 1AM PDT as far as I know. I usually log in either around noon or around 9PM (and get my stamps regardless of which time) , so I may not have noticed. I'll go ahead and try to corroborate that tomorrow.
EDIT: For reference, here are my logs:
