The trick involves connecting the console to the Internet mid-run, which causes the Switch to realize its clock is behind and fast-forward it accordingly. This can be used to fast-forward the clock twice by using Daylight Savings Time Abuse for the first advancement, and connecting to the Internet to use Network System Clock Abuse for the second advancement. Theoretically, it is possible to advance the clock a third time if the speedrun is done on the actual Daylight Savings Time day, by allowing DST to advance the clock a third time after it is synchronized to the real-world time. | The trick involves connecting the console to the Internet mid-run, which causes the Switch to realize its clock is behind and fast-forward it accordingly.

This is sometimes known as '''Triple DSTA''', but this is again a misnomer since only two of the clock advances utilize Daylight Savings Time. | ||

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). | 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 communication to all of Nintendo's servers, originally for the purpose of [[wikipedia:Homebrew_(video_games)|homebrew]].
