<paragraph id="par_id3153361" role="paragraph" xml-lang="en-US">Calculates a serial time value from the specified hour, minute, and second - parameters passed as strings - that represents the time in a single numeric value. This value can be used to calculate the difference between times.</paragraph>

<paragraph id="par_id3145786" role="paragraph" xml-lang="en-US"> <emph>Text:</emph> Any string expression that contains the time that you want to calculate in the format "HH:MM:SS".</paragraph>
<paragraph id="par_id3152578" role="paragraph" xml-lang="en-US">Use the TimeValue function to convert any time into a single value, so that you can calculate time differences.</paragraph>
<paragraph id="par_id3163710" role="paragraph" xml-lang="en-US">This TimeValue function returns the type Variant with VarType 7 (Date), and stores this value internally as a double-precision number between 0 and 0.9999999999.</paragraph>
<paragraph id="par_id3151117" role="paragraph" xml-lang="en-US">As opposed to the DateSerial or the DateValue function, where serial date values result in days relative to a fixed date, you can calculate with the values that are returned by the TimeValue function, but you cannot evaluate them.</paragraph>
<paragraph id="par_id3147426" role="paragraph" xml-lang="en-US">In the TimeSerial function, you can pass individual parameters (hour, minute, second) as separate numeric expressions. For the TimeValue function, however, you can pass a string as a parameter containing the time.</paragraph>
