Hours, minutes, and seconds may be any number (they shall not be limited to the ranges 0.24, Time is a subtype of number, where a time value of 1 = 1 day = 24 hours. In my opinion the very term "Returns the fraction of the day" using the definite article with "day" is showing that there is not much sense in this specification. It is focusing on the "Time Of Day" primarily, which is, on the other hand, incompatible with "they shall not be limited to the ranges 0.24, 0.59, or 0.60 respectively", also explicitly stated.
= 24 hours" is incompatible again, as TIME(24 0 0) will return 00:00:00, in fact. The calculation by the expression "((hours*60*60)+(minutes*60)+seconds)/(24*60*60)" seems sound for the first view, but cannot be applied without additional measures regarding the above statements. I claim this to be another case where we struggle with the consequences of refusing to make a necessary distinction.
The term "time" is misleadingly used as well for "time of day" (which is in itself an extremely complicated concept of everyday life), "duration" (not completely clear and often denoted in a misleadig way), and "time" in the technical or scientifical sense, replacing "duration" in the field, and also used as a variable where applicable. Think alone of the absurd complications caused in specific cases by the misconcept of "daylight saving time". I cannot imagine even an advanced spreadsheet handling this acceptably. We would need a thoroughly enhanced way of handling two specific cases every year: One where a complete hour is missing, and one where the TOD notation needs an apposition (a or b). This covering 2 h 0 min 0 s within each year, and thus 0.023% of all the time.The reference table below contains possible subtypes that may appear along with the following market items in the Conditions column of the Time & Sales window.:īy default, subtypes are highlighted in black with white text, unless otherwise noted.
