Time of when it is bought does not matter if the suppler has old stock.
You need to go by serial number, I think there was a guide somewhere about this.
Odds are though it came between 4.5+/-9.2
If it matters, I had a super mario brothers edition, yellow box, and it came with 8.1. At the time I needed to update to 9.2, luckily I updated the weekend before that Monday of the release 9.3
