Cross Midnight Benchmarks

Traditionally, VB programmers benchmark their code using the Timer function. However, if your process might terminate on the following day, you must take into account that the value returned by that function is reset at midnight. If you're satisfied with one-second precision, you can simplify your code using the Now function:
 
Dim startTime As Date
StartTime = Now
' the code to be benchmarked
' ...
Print "elapsedSeconds = " & Format$ _
        ((Now - startTime) * 86400, "#####")
You need the Format$ function to round the result to the nearest Integer.
