is it safe when your first offline play time before release too? i changed it but the first time is saved at the logs. can nintendo see the logs?
While they can probably see the logs, since the 3DS doesn't even have NTP (network time setting) support using the date and time to ban people would have quite a few false positives which is why they don't do it. There are no doubt quite a few people who skipped past setting the clock and never got around to it.
