Up to the time (5)
I believe the answer is:
until
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">up to the time</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for until that I've seen before include "As far as" , "Up to that moment" , "Unlit (anag.)" , "Up to (a point in time)" , "Not beyond (hour)" .)
