I believe the answer is:

year dot

(Other definitions for year dot that I've seen before include "Earliest known period" , "A very long time ago" , "As long ago as can be remembered" , "Start of time (colloq.)" , "Since this is as long as anyone can remember" .)

I've seen this clue in the Sydney Morning Herald.
