Otherwise you can create your own function then call it  It is important to use Double  Function sov sekunder As Double  As Double  starting time   Timer  Do DoEvents Loop Until  Timer - starting time   gt   sekunder  End Function

No answer helped me  so I build this       function Timestamp return current time in milliseconds      compatible with JSON or JavaScript Date objects   Public Function Timestamp    As Currency     timestamp    Round Now    0    24   60   60   Timer      1000 End Function      function Sleep let system execute other programs while the milliseconds are not elapsed   Public Function Sleep milliseconds As Currency       If milliseconds  lt  0 Then Exit Function      Dim start As Currency     start   Timestamp         While  Timestamp     lt  milliseconds   start          DoEvents     Wend End Function   Note   In Excel 2007  Now   send Double with decimals to seconds  so i use Timer   to get milliseconds   Note   Application Wait   accept seconds and no under  i e  Application Wait Now      Application Wait Now   100 millisecond     Note   Application Wait   doesn t let system execute other program but hardly reduce performance  Prefer usage of DoEvents

I have try this and it works for me   Private Sub DelayMs ms As Long      Debug Print TimeValue Now      Application Wait  Now    ms   0 00000001       Debug Print TimeValue Now  End Sub  Private Sub test       Call DelayMs  2000    test code with delay of 2 seconds  see debug window End Sub

Everyone tries Application Wait  but that s not really reliable  If you ask it to wait for less than a second  you ll get anything between 0 and 1  but closer to 10 seconds  Here s a demonstration using a wait of 0 5 seconds   Sub TestWait     Dim i As Long   For i   1 To 5     Dim t As Double     t   Timer     Application Wait Now   TimeValue  0 00 00     2     Debug Print Timer - t   Next End Sub   Here s the output  an average of 0 0015625 seconds   0 0 0 0 0078125 0   Admittedly  Timer may not be the ideal way to measure these events  but you get the idea   The Timer approach is better   Sub TestTimer     Dim i As Long   For i   1 To 5     Dim t As Double     t   Timer     Do Until Timer - t  gt   0 5       DoEvents     Loop     Debug Print Timer - t   Next End Sub   And the results average is very close to 0 5 seconds   0 5 0 5 0 5 0 5 0 5

You can use an API call and Sleep   Put this at the top of your module   Declare Sub Sleep Lib  kernel32   ByVal dwMilliseconds As Long    Then you can call it in a procedure like this   Sub test   Dim i As Long  For i   1 To 10     Debug Print Now       Sleep 500     wait 0 5 seconds Next i End Sub

Obviously an old post  but this seems to be working for me      Application Wait  Now   TimeValue  0 00 01     1000    Divide by whatever you need  A tenth  a hundredth  etc  all seem to work  By removing the  divide by  portion  the macro does take longer to run  so therefore  with no errors present  I have to believe it works

I found this on another site not sure if it works or not   Application Wait Now   1  24 60 60 0 2       the numerical value 1   1 day      1 24 is one hour      1  24 60  is one minute      so 1  24 60 60 2  is 1 2 second   You need to use a decimal point somewhere to force a floating point number  Source  Not sure if this will work worth a shot for milliseconds  Application Wait  Now   0 000001
