'''Network System Clock Abuse''', often abbreviated as '''NSCA''' and sometimes referred to as '''Double DSTA''', is a trick that allows the clock fast-forwarding effect achieved by [[Daylight Savings Time Abuse]] to be used a second time (and in some cases, a third) throughout a speedrun without opening the Switch's home menu. | '''Network System Clock Abuse''', often abbreviated as '''NSCA''' and sometimes referred to as '''Double DSTA''', is a trick that allows the clock fast-forwarding effect achieved by [[Daylight Savings Time Abuse]] to be used a second time (and in some cases, a third) throughout a speedrun without opening the Switch's home menu. This can be used to grow a seed quickly in the [[Metro Kingdom]] even after using Daylight Savings Time Abuse to grow one in the [[Sand Kingdom]] earlier in the run, saving about four seconds over the usual route<ref name="grady-tweet">https://twitter.com/grady964/status/1279144130052976640</ref>. | ||
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.

The Nintendo Switch keeps track of two separate system clocks<ref>https://twitter.com/SciresM/status/1231373584112635905</ref>. The one that the user directly interacts with is called the Local System Clock, or LSC. The user can edit the LSC directly in the system settings, and the LSC is also what Super Mario Odyssey uses to determine the time. When speedrunners set up [[Daylight Savings Time Abuse]], they are changing the value of the LSC. | The Nintendo Switch keeps track of two separate system clocks<ref>https://twitter.com/SciresM/status/1231373584112635905</ref>.
