You can also obtain the second of the minute by calling DatePart and specifying DateInterval.Second for the Interval argument.

The following example uses the Second function to obtain the second of the minute from a specified time. In the development environment, the time literal is displayed in short time format using the locale settings of your code.

Dim thisTime As Date
Dim thisSecond As Integer
thisTime = #4:35:17 PM#
thisSecond = Second(thisTime)
' thisSecond now contains 17.
