The Visual Basic Timer function can be used to record the starting and
ending times for a series of commands. The following example sets the
variable StartTime to the current system time, runs the code to be timed, and then sets the variable EndTime to the current system time. Finally, the
elapsed time between StartTime and EndTime is printed to the debug window
using the
Debug.Print command.

Sub ElapsedTime()
Dim StartTime As Double, EndTime As Double
'Stores start time in variable "StartTime"
StartTime = Timer
'Place your code to be timed here
'Stores end time in variable "EndTime"
EndTime = Timer
'Prints execution time in the debug window
Debug.Print "Execution time in seconds: ", EndTime - StartTime
End Sub
After you run the ElapsedTime macro, you can see the elapsed time in the
Immediate pane of the Debug window. To view the Immediate pane of the Debug
window, click

The following Visual Basic macro creates a text file containing a list of
error messages that can be generated in Visual Basic for Applications.
The amount of time it takes to accomplish this procedure is displayed
in a message box.
Visual Basic Sample Code
Sub ErrorCodes()
Dim StartTime As Double, EndTime As Double, X
'creates a file of error messages
StartTime = Timer 'Stores start time in variable "StartTime"
Open "vbaerror.txt" For Output As #1
For X = 1 To 3300
Print #1, X, Error$(X)
Next X
Close #1
EndTime = Timer 'Stores end time in variable "endTime"
'Shows Message Box with elapsed time
MsgBox "Execution time in seconds: " + Format$(EndTime - StartTime)
End Sub
