To explain this run I got lucky by having a spawn near the sea level so it made it easier to get to bedrock. In order to get the time that I did, I jitterclicked at about 20 - 25 cps.

Mod: Time starts at 13.867 and ends at 15.533 at 60 fps to get a final time of 0h 0m 1s 667ms. Retimed using yt-frame-timer
