Wait or Delay in VBA
There are many instances when a timer could be useful in Excel, here is one method to try:

Application.Wait Now + TimeValue("00:00:05")
MsgBox ("5 seconds")
End Sub

You can also use the methods above in Access VBA. For example, you might like to know how long it takes to move through a recordset.
Sub LoopThroughRecords()
Dim Count As Long
Dim BenchMark As Double
BenchMark = Timer
'Start of Code to Test
Set dbs = CurrentDb
Set rst = dbs.OpenRecordset("tblInvoices", dbOpenDynaset)
With rst
Do Until .EOF = True
.MoveNext
Loop
End With
'End of Code to Test
MsgBox "It took " & Timer - BenchMark & " seconds to loop"
End Sub
