Hi Ben

You can run this macro if you want to add a comment with date/time stamp or change the date/time in the comment.

Sub Test()
Dim cmt As Comment
Set cmt = ActiveCell.Comment
If cmt Is Nothing Then
ActiveCell.AddComment
ActiveCell.Comment.Text Text:=Format(Now, "dd-mmm-yy hh-mm-ss")
Else
If IsNumeric(Right(ActiveCell.Comment.Text, 2)) Then
ActiveCell.Comment.Text Text:=Left(ActiveCell.Comment.Text, Len(ActiveCell.Comment.Text) - 18) _
& Format(Now, "dd-mmm-yy h-mm-ss")
Else
ActiveCell.Comment.Text Text:=ActiveCell.Comment.Text & Chr(10) & Format(Now, "dd-mmm-yy hh-mm-ss")
End If
End If
End Sub
