Calculates a serial time value for the specified hour, minute, and second parameters that are passed as numeric value. You can then use this value to calculate the difference between times.
TimeSerial (hour, minute, second)
hour: Any integer expression that indicates the hour of the time that is used to determine the serial time value. Valid values: 0-23.
minute: Any integer expression that indicates the minute of the time that is used to determine the serial time value. In general, use values between 0 and 59. However, you can also use values that lie outside of this range, where the number of minutes influence the hour value.
second: Any integer expression that indicates the second of the time that is used to determine the serial time value. In general, you can use values between 0 and 59. However, you can also use values that lie outside of this range, where the number seconds influences the minute value.
12, -5, 45 atbilst 11, 55, 45
12, 61, 45 atbilst 13, 2, 45
12, 20, -2 atbilst 12, 19, 58
12, 20, 63 atbilst 12, 21, 4
You can use the TimeSerial function to convert any time into a single value that you can use to calculate time differences.
The TimeSerial function returns the type Variant with VarType 7 (Date). This value is stored internally as a double-precision number between 0 and 0.9999999999. As opposed to the DateSerial or DateValue function, where the serial date values are calculated as days relative to a fixed date, you can calculate with values returned by the TimeSerial function, but you cannot evaluate them.
In the TimeValue function, you can pass a string as a parameter containing the time. For the TimeSerial function, however, you can pass the individual parameters (hour, minute, second) as separate numeric expressions.
Dim dDate As Double, sDate As String
dDate = TimeSerial(8,30,15)
sDate = TimeSerial(8,30,15)
MsgBox dDate,64,"Time as a number"
MsgBox sDate,64,"Formatted time"
