The logical value in parentheses is 0 or 1, corresponding to 0 or 24 hours. The result returned by the formula is automatically issued in time format due to the sequence of the operands.</paragraph> 52<section id="relatedtopics"> 53<embed href="text/scalc/guide/calc_date.xhp#calc_date"/> 54</section> 55</body> 56</helpdocument> 57
