I believe the answer is:
point
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">exact moment</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for point that I've seen before include "Use" , "Sharp or tapering end" , "The whole idea" , "Fielder" , "Dot, punctuation mark" .)
