Hello yet again Karthi,

Your question prompted me to write some code that more fully covers timers.
It records the start time in cell A1, then the progressive time is displayed
in cell A2 and after the timer is stopped the total elapsed time is displayed
in cell A3.

Unlike the times entered as text with the format function as per my previous
post, these times can be added and subtracted etc (used in maths equations
etc).

You start the timer from Sub StartTiming()

Dim NextTick 'Must be declared in the declarations section before any subs.

Sub StartTiming()

Call StartClock

With ThisWorkbook.Sheets("Sheet1")
'Clear total elapsed time
.Range("A3").ClearContents

'Format the cells with time formats
.Range("A1:A3").NumberFormat = "hh:mm:ss"

'Save the start time in cell A1
.Range("A1").Value = Range("A2").Value

End With

End Sub

Sub StartClock()

With ThisWorkbook.Sheets("Sheet1")
.Range("A2") = Now()
End With

NextTick = Now + TimeValue("00:00:01")

Application.OnTime NextTick, "StartClock"
End Sub

Sub StopClock()
'Stop OnTime event.
'Returns error if already stopped and hense the on error handling.
On Error Resume Next

Application.OnTime _
EarliestTime:=NextTick, _
Procedu="StartClock", _
Schedule:=False

If Err.Number 0 Then Exit Sub

On Error GoTo 0
With ThisWorkbook.Sheets("Sheet1")
.Range("A3").Value _
= .Range("A2").Value - .Range("A1").Value
End With

End Sub
