If the Switch has been [https://en-americas-support.nintendo.com/app/answers/detail/a_id/22347/~/how-to-initialize-nintendo-switch-without-deleting-save-data initialized] and has not been connected to the Internet yet, the system simply matches the NSC to the LSC as a fail-safe. This means that if the console has never been connected to the Internet, the user can set the NSC to any desired value (in this case sometime in the past). The goal of this method is to calibrate the NSC for the first time in the middle of the speedrun. | If the Switch has been [https://en-americas-support.nintendo.com/app/answers/detail/a_id/22347/~/how-to-initialize-nintendo-switch-without-deleting-save-data initialized] and has not been connected to the Internet yet, the system simply matches the NSC to the LSC as a fail-safe.

To prevent it from being calibrated when setting up the Internet connection, one must temporarily block the Switch from communicating with Nintendo's [[wikipedia:Network_Time_Protocol|Network Time Protocol]] server. There are two ways to achieve this. | ||

The easiest way to block Nintendo's | The easiest way to block Nintendo's NTP server is using [https://nh-server.github.io/switch-guide/extras/blocking_nintendo/ 90DNS], a DNS server that is configured to block all of Nintendo's servers, originally for the purpose of [[wikipedia:Homebrew_(video_games)|homebrew]]. After establishing the connection with 90DNS, the DNS settings can be reverted to normal, and the Switch will not attempt to calibrate the NSC until the Switch is put to sleep and reawakened (at which point it can be put into Airplane Mode). | ||

This block must then be reversed later after enabling Airplane Mode, so that disabling Airplane Mode during the speedrun calibrates the NSC. | ||
