What was the fastest Speedrun ever on Speedrun.com and which game was speedrunned?

Probably the one we would consider the shortest by definition is minecraft classic break dirt which is 0ms (RTA) since its completed on the first frame and its the biggest tie at 600+ tied people However, theres many speedruns such as seterra new south wales and others where the wr is 0ms (shown as 1ms bc sr.c wont let you have 0ms as your time) even though most of these cases are a result of the IGT being manipulated or rounding down to the second

I think there are also Minesweeper runs where the starting input also solves the puzzle, resulting in a 0ms run.
